[Service] Make correctly smack label for some special service app

For some app like 111399000136, it's packagid is 'obxi69OqU7' which same with UI app's
package ID, but the service id is 'obxi69OqU4.service', if get packagid from service
name, 'obxi69OqU4' will get which is not 'obxi69OqU7'. So set smack label by service
app name, issue will happen.

Now get the packagid from webapis.getPackageId.
