In the patch posted, it was decided the best way to implement this whitelisting mechanism was through environment variable prior to `test-linux.sh` is called.

There are several environment variables that appear to denote if windowing manager is necessary, but they do not pertain to `compiz` specifically, so a new variable `NEED_COMPIZ` was created at `mozharness_test.py`.

The whitelist must be managed manually, which is a downside of this implementation.

Given that `compiz` on linux platforms eat up anywhere between 3-18 seconds due to the `restack` error, not starting compiz will potentially save us an amount comparable to that of the 15 second `sleep` removal from `test-linux.sh`.
