Repair failing test_sre.py.

This was a funny one!  The test very subtly relied on 1.5.2's
behavior of treating "\x%" as "\x%", i.e. ignoring that was an
\x escape that didn't make sense.  But /F implemented PEP 223,
which causes 2.0 to raise an exception on the bad escape.
Fixed by merely making the 3 such strings of this kind into
raw strings.
