kbuild: buildtar: remove warning for the default case

Given KBUILD_IMAGE properly set in arch/*/Makefile, the default case
should work in most scenarios. The only oddity is the naming of the
copy destination, vmlinux-kbuild-${KERNELRELEASE}. Let's rename it
to vmlinuz-${KERNELRELEASE} because the kernel is often compressed.
Remove the warning to avoid unnecessary patch submissions when the
default case suffices.

Remove the x86 case, which is now equivalent to the default.
