sna: Check for access to backlight interface

Before attaching properties to any connector, check that we can indeed
control the backlight through the sysfs interface by doing an access
check. If the xserver is started without root privileges, we cannot
write through /sys/class/backlight and so should take care not to
advertise that we can.
