WifiBackupRestore: Backup networks from apps holding CONFIG_OVERRIDE
We currently backup only networks created by system apps. Change that
to instead backup only networks created by apps holding the
|CONFIG_OVERRIDE| permission.
This will let us backup networks from apps like SetupWizard which
holds the |CONFIG_OVERRIDE| permission. Since such apps have the permission
to modify any network in the device, it doesn't matter that the |creatorUid|
info is lost during the restore process.
PS: See the discussion in b/29201888 for why the creatorUid cannot be
preserved across restore.
