Renamed test_hashlib_speed.py to time_hashlib.py.

Since it's never intended that this script be run by
regrtest.py, it shouldn't have been named with a "test_"
prefix to begin with.  A consequence is that we shouldn't
see useless:

    test_hashlib_speed skipped -- not a unit test (stand alone benchmark)

lines in regrtest output anymore.
