tests: adjust to the new format in pyflakes output

According to the pyflakes' NEWS.rst, the default output format changed
recently:

  2.2.0 (2020-04-08)
  - Include column information in error messages

So the lines now read:

  contrib/perf.py:149:15 undefined name 'xrange'
  mercurial/hgweb/server.py:427:13 undefined name 'reload'
  mercurial/util.py:2862:24 undefined name 'file'

This is a graft of a similar fix that ended up on default.
