Attemp to make mkv's AAC CSD data if codecprivate is short

Some mkv file's AAC codecprivate is incomplete, so
CHECK(codecPrivateSize >= 2) fails and it results in a
native exception. Our solution is to make it skip the
track.

Bug: 132738230
Test: Test a mkv file whose AAC codecprivate is short and
check if native exception occurs.
