Use jarjar rules for framework.jar.

Rather than copying the rules, boot libs (e.g. telephony-common
or those added by OEMs) can just add the following to their library:
    jarjar_rules: ":framework-jarjar-rules",

This will ensure that rules can be changed in framework.jar without
breaking things downstream.
