meck doesn't build. Maybe move it to a test env?

This is a bare project with only quaff as it's dep.

Give meck is a mock library I'm guessing you aren't using it for more than testing. Perhaps you could add it as a dep only when testing? Hear is an example of that:

Turns out meck won't build under Erlang 17.0rc2. I put in a pull request to fix that

Fix underway in build_updates2 branch; I'll add 17.0 (rc1, because that's what they have) to the travis build configs once that pull request is accepted.

meck is now only a test dep, for both rebar and mix builds; I've also added E17 to the test matrix.
