Block adb from changing certain settings value when corresponding user ...
restriction is on.
Check calling uid in isSettingRestrictedForUser(which is called by settingsprovider),
and only allow system_uid when certain user restriction is on, so that user won't be
able to change these settings with adb:
Settings.Secure.LOCATION_MODE,
Settings.Secure.PROVIDERS_ALLOWED,
Settings.System.SCREEN_BRIGHTNESS,
Settings.System.SCREEN_BRIGHTNESS_MODE,
Settings.System.SCREEN_OFF_TIMEOUT,
Settings.Global.AUTO_TIME,
Settings.Global.AUTO_TIME_ZONE.
This check also prevents 3rd party apps from modifying system settings value
when corresponding user restriction is on.
In addition, any attempt to change AUTO_TIME will also go through the check
for dpm.getAutoTimeRequired().
Test: manually by running the adb command with restriction set and not set
