Add headless tests to main trybots

Adds network_service_headless_browsertests and headless_python_unittests
to the main set of chromium gtests. These suites are pretty quick to
run, and the headless bot which used to run them is being deleted. This
ensures these tests continue to run.

Also disables a test which fails on ASAN.
