plugin/builder: silence some pylint warnings

The 'koji' parameter for the compose request is called that way to
follow the OpenAPI spec, so silence the "redefined-outer-name"
warning.

The handler function needs have the actual task arguments and thus
on purpose deviates from the argument list of the base class'
handler method. So silence that.
