[Brightness] GMenu2X and FunKey overlay do not use the same setting.

[DrUm78]

GMenu2X and FunKey overlay do not use the same setting, which leads to some conflict between those 2 values (pressing "Start" to display GMenu2X serttings will restore the brightness to GMenu2X value).

Steps to reproduce:

1. Set brightness value to 5 for instance in GMenu2x (Start button)
2. Press Start to exit GMenu2x settings
3. Use Menu button to modify brightness or Fn+X/B shortcut
4. Press Start key twice (open/close Gmenu2X menu)
5. Notice that brightness state is now restored to GMenu2X previous value

Expected behavior:
The brightness value should be shared between GMenu2X and the Funkey overlay and both should impact the other.

Under /sys/class/backlight/ there should be the "VIDEO" device directories with brightness and max_brightness therein.

Knowing that, it should be possible to (using shell examples) :
current_brightness = $(cat /sys/class/backlight/VIDEODEV/brightness) # for displaying current level

[[ $set_brightness -lt $(cat /sys/class/backlight/VIDEODEV/max_brightness) ]] && echo $set_brightness > /sys/class/backlight/VIDEODEV/brightness # to set the level

So it should likely be feasible for the menu system & EMUs to have consistent Brightness management.

Thanks for the suggestion, I was not sure that communication between GMenu2X and the system brightness setting was possible. :)

I fixed it by disabling the code and removing the option in GMenu2X: DrUm78/gmenu2x@4fc3eed

No need to have 3 places to set brightness (FK shortcuts, FK menu and GMenu2X options).
Now, the brightness stays consistent when entering GMenu2X option menu.
