poky-alt: don't use conditional assignment for preferred kernel version

The include of poky.conf already sets a preferred kernel version, so the
one in the alt-config won't have any impact.

This normally isn't a problem, but when we are introducing a new kernel
that doesn't yet have compatibility with all machines, it throws warnings.

 WARNING: preferred version 5.10% of linux-yocto not available (for item kernel-module-x-tables)
 WARNING: versions of linux-yocto available: 5.4.69+gitAUTOINC+1c358e1969_cfcdd63145 5.8.13+gitAUTOINC+b976de4f41_5981001bf0
