Add 'CFI ThinLTO Linux ToT' buildbot (src part).

We're close to replace FullLTO and CFI with FullLTO with
their ThinLTO counterparts. This should reduce linking time
by 2x-3x, and open a road for even better gains.

This particular change sets up a bot that tests for CFI+ThinLTO.
Eventually, when we switch the desktop build to ThinLTO, we'll
retire all ThinLTO bots and make CFI/LTO bots to imply ThinLTO.
