Stop restricting the sender object path for incoming signals.

Stop restricting the sender object path for incoming signals.

Restricting the sender path makes it impossible to test
signal handling with dbus-send --type=signal, as it uses
"/" as the sender object path. 

For now, let's remove the restriction. We can make this restriction
customizable when it becomes necessary.

This works to restore dbus injection to
<http://codereview.chromium.org/7862020>. As far as my looking goes, it looks
good.

Thanks!
