functions: refactor add_module

Simplify and fix a few bugs in the process. We rely solely on modinfo
for obtaining information about module location, dependencies and
firmware. Add a small wrapper function for modinfo that will always
specify our $BASEDIR and $KERNELVERSION for us.

Also, kill off HAS_MODULES. Since we have ADDED_MODULES, which contains
all currently added modules, we can count the elements in this when it
comes time to decide to create depmod files.
