bug#22952: Backlight brightness keys in GDM and MATE require password au

I’m reopening this bug because it is very similar to my issue.

When using my Macbook’s keyboard XF86MonBrightnessUp/Down keys to
adjust screen brightness (probably on non-Macbooks too) in GDM or
MATE, I am asked to enter my authentication password to make
gnome-settings-daemon’s libexec/gsd-backlight-helper (or some
equivalent program on MATE) change screen brightness.

This should not be so; gsd-backlight-helper should have PolicyKit, pam
or setuid or whatever.

Regards,
Florian
