Subject: Make modload calculate a reasonable default entry point name, in
 light of the recent changes to bsd.kmod.mk, which enforces that the entry
 point be <modname>_mod, unless overridden.

This means that when modloading "/lkm/foo_mod.o", it'll use "foo_mod"
as the default entry point (instead of xxxinit) unless you specify
another via the -e option.
