Use WeakPtr to simplify the DBUS Timeout helper.

The internal Timeout wrapper for DBusTimeout was previously ref-counted
to ensure that it was still valid when HandleTimeout fires. This CL adds
a WeakPtrFactory to Timeout, allowing it to be safely deleted when the
corresponding DBusTimeout is removed, with HandleTimeout becoming a
no-op.
