linux-mod-r1.eclass: Add USE=modules-compress
Add a `modules-compress` USE flag to explicitly control kernel module
compression. When the flag is disabled, modules are installed
uncompressed even if the kernel supports compression (which is going
to be the case for new sys-kernel/gentoo-kernel* builds). When it is
enabled, the eclass compresses modules using the compressor configured,
or fails if no compression is supported.
