Download media parser test: Restrict on phone.

On Nexus 7 devices on Android version M, L, K, when decoding H264 video
thumbnail, the OEM decoder may not response, currently it will time out
and fail in 8 seconds.

This CL restricts the H264 test to run on phone. A better solution is
still needed in the future.
