Ben Nemec 6377c723aa Allow elements to add drivers to dracut
It is reasonable that elements may need to include additional
kernel modules in a dracut ramdisk.  This is done with the
--add-drivers option to dracut, but previously the value passed
was hard-coded.

This change allows an element to put a file containing its desired
drivers in a dracut-drivers.d directory, and the list there will
be added to the list of drivers added.  This functions in
essentially the same way as the binary-deps.d directory that
already exists for including additional executables in a ramdisk.
