Remove duplicate binary-deps from dracut-ramdisk

These are already listed in the respective deploy-* elements, and
if we include them here then they get added to every ramdisk built
with dracut.  That causes issues for elements that don't need
something like tgtd because it won't be installed and the
binary deps script will fail.
