Adapting pylint runner to the new message format

Pareseable output format and --include-ids parameter are deprecated
and ignored in the pylint version used on the gate.
These functions are replaced by the --msg-template parameter.

This patch changes the runner to use the new parameter so that the
job can run properly on the gate
