rubinius name on travis rvm matrix has changed

Started seeing this earlier in the week, and just noticed a discussion
on the travis-ci issues list today: https://github.com/travis-ci/travis-ci/issues/1641

Seems like using rbx and rbx2 are the two supported versions right now.
Ideally rbx-19mode would still work so we can explicitly say which version
of ruby under rubinius we want, but alas.
Make tests pass under rubinius

A little surprised by the extent of gems that are not included in
the standard lib, but that's the state of the rubinius world. It
seems that rubinius is still difficult to maintain compatibility
with, but I've noticed (and been told before) that rubinius does help
expose bugs that other rubies will cover up, so I'm willing to personally
invest this time.
