Only build-depend on fail with ancient GHC #213

Is this causing any problems? The fail package is designed to have almost no cost for base >= 4.9 so it can be depended upon unconditionally...

We don't have empty packages in Debian so any uses of them (fail, nats, bytestring-builder, etc.) need to be patched out which leads to a lot of wasted labor that needs to be repeated on every package upgrade. Things like semigroups are okay because they're not completely empty.
