iotests: split linters.py out from 297

Now, 297 is just the iotests-specific incantations and linters.py is as
minimal as I can think to make it. The only remaining element in here
that ought to be configuration and not code is the list of skip files,
but they're still numerous enough that repeating them for mypy and
pylint configurations both would be ... a hassle.

iotests/297: Change run_linter() to raise an exception on failure

Instead of using a process return code as the python function return
value (or just not returning anything at all), allow run_linter() to
raise an exception instead.

The responsibility for printing output on error shifts from the function
itself to the caller, who will know best how to present/format that
information. (Also, "suppress_output" is now a lot more accurate of a
parameter name.)

iotests/297: Don't rely on distro-specific linter binaries

'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'.

So, if you plan on using any, you have to pass
