No longer checking 1080p in QtKit for WebRTC webcam tests.

No longer checking 1080p in QtKit for WebRTC webcam tests.

QtKit doesn't support 1080p, which I found out when I enabled our C920-
equipped mac bot. Therefore we will no longer try to test that.

Also temporarily disabling QVGA for qtkit since it incorrectly acquires
320x180 rather than 320x240.
