CanvasDRM: Fix handling of Ctrl-C. Because the Ctrl-C was being handled by
CanvasDRM directly, DRMState had no knowledge of the event, and wasn't able
to detect it properly when select() came back with an error. Move the
quit handler into DRMState, and give it a public should_quit() method that
CanvasDRM can call. This is better encapsulation, and allows DRMState to
properly detect the user interrupt and release the GBM resources so the
console isn't hung when the application exits.
