This patch fixes some issues in classes providing cpan module build support:

* add support even for xs modules with more than 3 levels as
  B::Hooks::End::Of::Scope or Math::Random::ISAAC::XS
* correct handling of Module::Build (as far as stolen from pkgsrc
  and my humble knowledge)
* configure to install to vendor_libs as default, even when
  inherited do_install remains unused (overwritten do_install)

The previous fix for this same issue (OE-Core rev
f31f6a70ec24e8c9515d69c5092e15effc5e7d4d) was not sufficient - we are
setting the PERLVERSION variable from the get_perl_version function, but
we're setting it using immediate expansion; thus the value is going into
the signature and is still different between the time the recipe is
cached on an empty TMPDIR and after perl is in the sysroot and we run
bitbake -S perf. We could remove the immediate expansion, but that would
mean the get_perl_version function would be called more often, so just set
vardepvalue on the PERLVERSION variable to fix the problem instead.

* without this bitbake -S perf shows following error:
  ERROR: Bitbake's cached basehash does not match the one we just generated
    (/OE/oe-core/meta/recipes-kernel/perf/perf.bb.do_package)!
  if you run it twice, once without perl in sysroot and once with perl
  already built

We seem to be mostly installing modules into vendor_perl nowadays.
Make sure that the .debug data from there is captured appropriately.

Also, expand ${PERLLIBDIRS} at the point of assignment so we don't
call the python again and again.

Using "1" with getVar is bad coding style and "True" is preferred.
This patch is a sed over the meta directory of the form:

sed \
 -e 's:\(\.getVar([^,()]*, \)1 *):\1True):g' \
 -e 's:\(\.getVarFlag([^,()]*, [^,()]*, \)1 *):\1True):g' \
 -i `grep -ril getVar *`

This is the result of running the following over the metadata:

sed \
-e 's:bb.data.\(setVar([^,()]*,[^,()]*\), *\([^ )]*\) *):\2.\1):g' \
-e 's:bb.data.\(setVarFlag([^,()]*,[^,()]*,[^,()]*\), *\([^) ]*\) *):\2.\1):g' \

Since perl-native now populates into its own dir, here we need
change accordingly.
