test/py: Use raw strings more to avoid deprecation warnings
We have two further uses of raw string usage in the test/py codebase
that are used under CI. The first of which is under the bind test and
is a direct update. The second of which is to strip VT100 codes from
the match buffer. While switching this to a raw string is also a direct
update, the comment it notes that problems were encountered on Ubuntu
14.04 (and whatever Python 2 version that was) that required slight
tweaks to the regex. Replace that now that we're saying Python 3.5 is
the minimum.
