config: limit the kernel subsystems we look for devices in
Don't enumerate/monitor all devices of the system (since that can be
quite a few), but limit our search to devices from the "input"
subsystem, as well as the "tty" subsystem (to cover Wacom tablets).
This should make X start up a bit faster and reduce the number of
unnecessary wake-ups of the X server.
