Subject: [PATCH] kubernetes: get it working on AArch64 as well

In past I disabled those images on non-x86 because had lot of other
things to do. Now it is time to get it running on aarch64 too.

Had to revert rename done in 5a530be776c4897523e3419e69d798de0dc1755c
so backward compatibility is broken ;(
