Modify instmods to not rely on the existence of modules.* files

This patch series aims to make dracut more distro-independent.  It includes
some of the functionality that Seewer Philippe posted to the list to make
dracut work on Ubuntu.

depmod does not create these files on all distros (Debian, specifically),
so modify instmods to use pathname components and find to do what we want.

As a bonus, this removes the special-case for =ata.
