firewalld: Add D-Bus ObjectManager to track the Firewalld service lifetime
Added ObjectManager to firewalld to allow permission_broker to track the
lifetime of the top D-Bus service object and restart permission_broker
if firewall crashes/restarts.
This will also allow to wait for Firewalld to come up and finish initialization
before permission_broker D-Bus appears on the bus, which would eliminate
weird race condiftions when web server asks permission_broker to open
TCP ports too early (before firewalld is up and running).
BUG=brillo:1240
TEST=`FEATURES=test emerge-link firewalld permission_broker apmanager webserver`
