Description: test against the current python versions, not hard-coded ones
 Upstream test suite is testing against python2.7 and python3.5 at
 build-time.  Fix this to test against 'python' and 'python3' to use
 whatever the current Debian default is for this release, instead of
 hard-coding a specific version number.
