Remove gesture.config_is_trustworthy pref

Remove gesture.config_is_trustworthy pref

gesture.config_is_trustworthy pref is a temporary flag added in M30 to
do a one-time wipe of gesture config prefs. After two milestones, the
prefs should have been wiped for a good majority of users. So, the flag
is not needed anymore.
