string when KERNEL_VERSION is set.

Thanks, this is a clear bug.

meta/lib/oeqa/selftest/cases/uki.py could be improved to cover this.
I would be interested to know if the kernel version autodetection
does not work since that is preferred by ukify.py and this KERNEL_VERSION
handling in uki.bbclass could be removed.

It works for me now. I just ran into this bug while trying different class
variables. In the end I had build misconfigured in other places (missing efi
machine feature and possible some other stuff).
