Revert "Retrieve service, rpc and protcol entries via getent in hostonly mode"

The underlying issues this was trying to solve is to get a cheap
workaround for the fact that (open)SUSE with atomic support moved
/etc stock files to /usr/etc in order to improve compatibility. But
now that even nsswitch.conf moved, this is no longer enough. And it
might be more trouble to support once it's in an official release.

So let's rather drop it now.

This reverts commit e0524af2bf.
