Fix brightness not restoring when an inhibition is active

BUG: 352497

An active inhibition with ChangeScreenSettings policy won't
allow to restore dimmed screen brightness normally. In this
case the user will be left with a barely visible screen,
requiring him/her to manually adjust the brightness back to

This commit enforces dimmed screen brightness restoration
even if ChangeScreenSettings policy is unavailable.
