Add Open Screen unit tests

This patch adds additional dependencies on Open Screen to enable running
unit tests inside of Chrome.

This adds a new openscreen_unittests target
and adds it to the builders.

The following TODO is also added:
TODO(crbug.com/1025244): Move Open Screen unit tests from fieldtrial
to linux, mac bots once we have ensured the tests are stable.
