Fix various issues in the roll_gn script.

This patch address a bunch of issues people have found in the roll_gn script:

- Fixes yet another bug where we weren't waiting for the try jobs
  to finish.
- Fixes a bug where we were adding an extra '\n' onto the DEPS file
  in the final roll CL.
- Closes the 'build_gn' CL once the build has completed.
- Adds better logging at the end of the 'wait' and 'roll_buildtools' steps.
- Removes mac_chromium_gn_rel from CQ_EXTRA_TRYBOTS, since
  it is part of the default set now.
