Firefox need access to org.freedesktop.resolve1 ResolvehostName

[Franck]

In 16.10, FF 49.0, it seems that Firefox want to use the systemd resolved service via dbus:

audit: type=1107 audit(1476778477.837:122): pid=3449 uid=105 auid=4294967295 ses=4294967295 msg='apparmor="DENIED" operation="dbus_method_call" bus="system" path="/org/freedesktop/resolve1" interface="org.freedesktop.resolve1.Manager" member="ResolveHostname" mask="send" name="org.freedesktop.resolve1" pid=9652 label="/usr/lib/firefox/firefox{,*[^s][^h]}" peer_pid=3909 peer_label="unconfined"
