Subject: [PATCH] Revert "kbuild: Hack for depmod not handling X.Y versions"

Remove hack for ancient version of module-init-tools that was added in
Linux 3.0.

Since then module-init-tools was replaced with kmod.

This hack adds an additional indirection, and causes confusing errors
to be printed when depmod fails.
