Systemd is failing trying to load kdbus [1] because kmod have
an error in return code when try to insert module [2].

This change of SRCREV is a MINOR one only include the fix
described.

If base_bindir is not a direct child of / the link creation in
do_install_append creates incorrect relative links.

Instead pass a full path to the link source too the lnr script
to create a relative link.

Confirmed with the author Qi, it isn't needed.

The following patches are rebased.
-- Change-to-calling-bswap_-instead-of-htobe-and-be-toh.patch
-- avoid_parallel_tests.patch

The ptest part of kmod is removed because new version of kmod port all tests to
use modules from module-playground instead of copying prebuilt modules to the
repository. So, we cannot use ptest as before. Remove it so that kmod can build
successfully.

Using populate_sysroot for this data was a nice idea but flawed as it
doesn't work in multilib builds. Instead we can use PKGDATA_DIR since
this is consistent over multilib builds. It also turns out to be
slightly neater code too. Hopefully this resolves the problem once and
for all.

debug and logging will make kmod and its library bigger than expected
due many strings in the resulting binaries. While these are useful for
development, they are of no use for deployment.

With them enabled kmod is 154Kb, libkmod is 99Kb. Disabling reduces to
kmod 139Kb (10%) and libkmod 83Kb (19%) on i586 stripped.

With the rpm package backend enabled, running:

bitbake <image>
bitbake virtual/kernel -c clean
bitbake <image> -c rootfs -f

results in an image with incorrect kernel module dependency information.
The problem is that the System.map and kernel-abiversion files are needed
for depmod and after the recent kernel changes, these are no longer in
sstate.

Its reasonable to require the kernel to unpack/build if you're
about to build a module against it. It is not reasonable to require this
just to build a rootfs.

Therefore stash the needed files specifically for depmod.

Also fix some STAGING_KERNEL_DIR references which were incorrect, found
whilst sorting through his change.
