Disable Hydra builds for obsolete Haskell packages.

travis build: Revert silly idea

nox-review should review against master, it's travis that should check out a hydra-available master commit to set the PR on. Perhaps we could rebase the current HEAD on the hydra-built commitish instead?

I wish I had a travis test environment :sad:
