Add target in Makefile to compress the module after it's installed.
Module-init-tools and libkmod can handle gzipped modules.

I am not convinced that this is a needed feature. Compressing elf files
means that depmod and modinfo need to read the whole compressed file
from disk and unpack it, while only a couple of bytes need to be read.

How many times do you need to call depmod / modinfo?

The operation that is used most of the time is to load modules. The
reason for having modules gzipped is the same one as for kernel image:
fast bootup on slow disks and less disk space used per installed
kernel.
