Convert common.RunAndWait method to raise an exception on subprocess failure.
Then refactor the code in merge_target_files.py to adapt to this semantic change. This makes the code more consistent with existing releasetools code, and it's easier to follow. Test: Failure cases (verify exception), success cases (merged target generated) Bug: 124521133 Change-Id: I56f04e360d8ff8ffcd6245359cdeb79f4565a9c4
