Why do you need to post this to the message loop on the same thread? Can we just
call RequestOwnership() here?

Hmm, 
Calling bus->RequestOwnership() here causes check failure at 
dbus::Bus::AssertOnOriginThread() in
dbus::Bus::RequestOwnership
.

TestService::RequestOwnership is called from the main thread in
SignalSenderVerificationTest, so I think we need to do this.
