cairo: Include command name in error messages.

Commit ddb7b52128d8 (output: Make errors, warnings, and notes into a new
"message_item".) changed command name tracking to a responsibility of
individual output drivers, and converted the output drivers to do it.
However, the conversion of the cairo driver was incomplete.  This commit
fixes that problem.
