[PULL 05/22] iotests/297: Don't rely on distro-specific linter binaries

[John Snow <jsnow@redhat.com>]

'pylint-3' is another Fedora-ism. Use "python3 -m pylint" or "python3 -m
mypy" to access these scripts instead. This style of invocation will
prefer the "correct" tool when run in a virtual environment.

Note that we still check for "pylint-3" before the test begins -- this
check is now "overly strict", but shouldn't cause anything that was
already running correctly to start failing. This is addressed by a
commit later in this series;
  'iotests/297: update tool availability checks'.
