intel: Add a helper for setting backlight without root rights
Once the xserver stops running as root on kms capabable systems, we will need
some other way to access the backlight.
The approach taken in this patch moves most of the heavy lifting to a
helper that runs with root privileges and pipes our requested brightness
into the sysfs backlight interface. Where required, we use pkexec to
launch the helper with the elevated privilege.
v2: Amalgamate much more of the duplicate code.
Keep the daemon and pipe alive for the lifetime of the backlight interface.
Provide an alternative for systems without PolicyKit.
