Rationale: testsuite didn't covered the "kmod(vboxdrv.ko)" provides.
So we were skipping eg virtualbox-kernel-6.0.9-desktop-1.mga9 because it
provided "kmod(vboxdrv.ko)[== 7.0.4]" which was needed because
virtualbox-7.0.4-1.mga9.x86_64 requires "kmod(vboxdrv.ko)"

We need a better fix as in check if a (non orphaned) pkg still provides
the property instead.

Only build updated kernel pkgs for faster kernel ophan testing

Kernel naming as used in mga9+: each kernel is named "kernel".
So we can have multiple packages named "kernel" installed at the same
time, with different versions

It now works with previous commit.

Now kernel names are unversionned and we've multiple packages with the
same "kernel" name which make orphans handling to derail

Rationale: so that we can document kernel management
