[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.
