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.)
