deviceorientation events not firing on devices without gyroscopes

Duplicate of bug: 1318293
Reopening this and deduping from bug 1318293; it looks like this is an actual regression in how we handle device orientation on phones without gyroscopes.

Summary: I can not listen for orientation anymore → deviceorientation events not firing on devices without gyroscopes
gal007, if you get a chance, can you try out demo2.html (attached on the bug) on your device and let me know what you see? It's the same demo, but listening for "absolutedeviceorientation" rather than "deviceorientation" -- if you get expected results here, then I'm pretty sure we're failing to fall through to other sensors when a gyroscope is not present.
Eugen, flagging you for review on this since you touched it last. I think we need to enable SENSOR_ROTATION_VECTOR events for deviceorientation events for backward compatibility with phones that don't fire SENSOR_GAME_ROTATION_VECTOR events here. Tested by ignoring SENSOR_GAME_ROTATION_VECTOR events in GeckoAppShell.onSensorChanged() -- without the patch we never fire ondeviceorientation, with the patch we fire it as expected.
