Add test for MediaExtractor entry point collection

Note: This patch also disables a broken
MediaSessionManagerHostTest.

The test is a hostside test, and checks against statsd output.
- Makes an on-device app extract a sample media file using
  Java (SDK MediaExtractor), C++ (NDK, on the JNI thread) and
  C++ (NDK, on a std::thread).
- Then checks that the generated statsd atom reports the correct
  entry point.
