Title: [WIP] Disable duplicate CommonCrypto test runs on Travis

The Travis OS X jobs are run for two versions of OpenSSL, but we only need to run the CommonCrypto backend tests once.

This should speed up our full test suite run times by a decent amount, but does come at the cost of an increasingly complex set of travis scripts.
