Previously only one global variant of the script was created,
which caused numerous issues:

1) multilib was not properly supported due to multilib variants each
needing their own version of the qemu binary and library paths to be set
2) nativesdk was not properly supported for the same reason

This patch also moves setting LD_LIBRARY_PATH directly into the
recipe, as passing it down from other recipes did not work when
said recipes were allarch, and adjusts calls to qemuwrapper from
postinst-intercepts, so that its correct variant is selected.

Also, the various qemu fallbacks in qemuwrapper script are all removed,
as they are no longer necessary.

Qemu is used to run fc-cache on postinstall.

getVar() now defaults to expanding by default, thus remove the True
option from getVar() calls with a regex search and replace.

Search made with the following regex: getVar ?\(( ?[^,()]*), True\)

* this can be useful for passing extra parameters, pass
  -v by default to see what's going on in do_rootfs
* we need to use this for extra parameter we implemented
  in fontconfig:
  --ignore-mtime always use cache file regardless of font directory mtime
  because the checksum of fontcache generated in do_rootfs
  doesn't match with /usr/share/fonts directory as seen on
  target device causing fontconfig to re-create the cache
  when fontconfig is used for first time or worse create
  new cache in every user's home directory when /usr/
  filesystem is read only and cache cannot be updated.

  Running FC_DEBUG=16 fc-cache -v on such device shows:
  FcCacheTimeValid dir "/usr/share/fonts" cache checksum 1441207803 dir checksum 1441206149
* my guess is that the checksum is different, because pseudo
  (which is unloaded when running qemuwrapper) or because some
  influence of running the rootfs under qemu.

Appending to PACKAGEFUNCS results in the font packages missing the
postinst/postrm scripts and the fontconfig cache not being generated
in /var/cache/fontconfig when creating images or installing font
packages. This is because the package data has already been emitted
by emit_pkgdata in PACKAGEFUNCS. Prepend to PACKAGEFUNCS to ensure
add_fontcache_postinsts is executed before emit_pkgdata.

The file ownership of the cache files in /var/cache/fontconfig needs to
be set to root:root otherwise it inherits the user and group id of the
build user.

This addresses warnings like:

WARNING: QA Issue: liberation-fonts rdepends on fontconfig-utils but its not a build dependency? [build-deps]

since the dependencies were being added at package time and were not
visible to bitbake.

Also take the opportunity to convert to use PACKAGEFUNCS rather than
the horrible populate_packages_append.

In an image recipe, you can get a warning, for example:
WARNING: The postinstall intercept hook 'update_font_cache' failed (exit code: 1)! See log for details!
WARNING: The postinstalls for the following packages will be postponed for first boot: ttf-dejavu-sans-mono

(because /usr/bin/fc-cache is missing)

In OE-core, rdepend is correctly done in each recipe:
- ttf-fonts/liberation-fonts
- ttf-fonts/ttf-bitstream-vera

In meta-OE, rdepend is not done but packagegroup-fonts-truetype.bb includes fontconfig-utils:
- ttf-fonts/ttf-arphic-uming
- ttf-fonts/ttf-dejavu
- ttf-fonts/ttf-droid
- ttf-fonts/ttf-gentium
- ttf-fonts/ttf-hunkyfonts
- ttf-fonts/ttf-inconsolata
- ttf-fonts/ttf-liberation
- ttf-fonts/ttf-mplus
- ttf-fonts/ttf-sazanami
- ttf-fonts/ttf-ubuntu-font-family
- ttf-fonts/ttf-wqy-zenhei
