sysmenu: fix luminance calculation, and allow going above preset 5 in many cases.

Browse Source 
Unlike SetLuminanceLevel, SetLuminance doesn't check if preset <= 5, and actually allows the lumiance levels provisioned for the "brightness boost mode" (brighter when adapter is plugged in), even when the feature is disabled (it is disabled for anything but the OG model, iirc).
