kernel-{build,install}.eclass: Support XZ module compression
When KERNEL_IUSE_GENERIC_UKI is set (to gatekeep for new ebuilds),
enable XZ module compression in kernel and add IUSE=module-compress.
When the flag is enabled, the modules are installed .xz compressed
per the config. When it is disabled, they are installed uncompressed
but the kernel retains module compression support.
