kernel-install.eclass: use dist-kernel_get_module_suffix to find compression
Adjusts kernel-install_compress_modules to use the new function
dist-kernel_get_module_suffix. This makes no functional difference
at the moment since gentoo-kernel-bin is the only consumer and it has
XZ compression in the config. Still this makes it possible to compile
alternate prebuilt kernels with alternate module compression support, and may
in the future help to support gzip and zstd module compression in
gentoo-kernel-bin.
