Rename test_ file that is really a support file to remove test_ prefix.
I thought I had run the full test suite before the last checkin, but
obviously I didn't. test_multibytecodec_support.py isn't really a test file,
it is a support file that contains a base test class. Rename it to
multibytecodec_support so that regrtest test discovery doesn't think it is a
test file that should be run.
