conf: fix meta-virt version / config include

As was reported:

https://lists.yoctoproject.org/g/meta-virtualization/message/4173?p=,,,20,0,0,0::Created,,conf%2Flayer.conf+is+broken,20,2,0,61269733

The conditional include of the meta-virt versions and config was not
working properly due to parse time constraints.

This commit fixes that by following the example of the meta-cube layer
and instead using a user bbclass to load the .inc file after
distro/distro features have been resolved by bitbake.
