1782793 - Provide a friendly error message that `./mach test --headless` doesn't work on Android

Status: NEW

--headless is not supported. But it doesn't tell you that; you need to adb logcat and find in the large amount of output the message "GeckoRuntime: Error: headless mode is not currently supported on this platform."

It would be nice to be more upfront about this.

Sounds like you'd like the test harness to error out earlier? That seems fair. It's a little tricky 'cuz all of the harnesses handle arguments differently, but we could anticipate Android and --headless around here.
