Revert "Add basic backlight percentage support"
On OpenBSD the backlight percentage cannot be retrieved in a simple way.
The only two solutions we are aware of for now are:
- reading from /dev/ttyC0: which isn't possible without changing
permissions or running slstatus as root
- linking against xcb-xrandr: which is bloat and does not work in every
case appearently
This reverts commit 37724ac2c3
for now.
