The version of powerdevil we're using prints a few debug messages every time an
inhibition is triggered, including some spurious messages about not being able
to contact consolekit. This can cause a lot of spam in the system journal,
especially when a web browser or other application that plays video is running,
because such applications often trigger such inhibitions very frequently.
A recent upstream commit to powerdevil changes the logging behavior of the
program so that it doesn't print debug messages anymore. This commit backports
that patch to our version of powerdevil (5.17.5).
