Have travis take shallow clones of the repo (#10275)

Just cloning TS on travis takes 23 seconds on linux (68 seconds on mac), hopefully having it do a shallow clone will help.

We don't rely on any tagging/artifacts from the travis servers which clone depth could impact, so this shouldn't impact anything other than build speed.
