[redhat] configs: Compress kernel with zstd cleanup
Zstd compressed kernels consume less disk space and decompress faster
than gziped ones. For example, kernel 6.12rc3 aarch64's on disk size
is ~22% smaller and boots ~16% faster on a RPi4. Since this was
already on for some x86 flavors, lets propogate the setting to all
appropriate architectures and kernel flavors.
