[MS15.1] Remove get/setSubscriberIdMatchRule dependencies

Subscriber Id Match Rule won't be exposed as system Api.
Callers should use Builder#setSubscriberIds or
NetworkTemplate#getSubscriberIds to set/get the Subscriber
Ids filter. An empty set in the paremter or return value
represents the intention of matching any Subscriber Ids.
