Switch SessionManagerClient::RestartJob to use RestartJobWithAuth
Switch SessionManagerClient::RestartJob to use RestartJobWithAuth

The session manager is once again providing a RestartJobWithAuth
method to allow callers to directly authorize their request to
restart the browser by providing a unix domain socket ready to be
SO_PEERCREDified in lieu of a pid.

This has the advantage of working inside a PID namespace, while
normal dbus mechanisms do not.
