Revert change to D-Bus API.

The D-Bus API signal CheckerCompleted is documented to provide a
wait(2) status value.  Since the server switched to using subprocess
to run checkers, it no longer has access to a wait(2) status value.  A
previous change to work around this made the D-Bus API incompatible.
Revert this change by constructing a fake wait(2) status value; this
keeps the D-Bus API stable.

* DBUS-API (CheckerCompleted): Revert incompatible change.
* mandos (ClientDBus.checker_callback): Construct fake wait(2) status.
* mandos-monitor (MandosClientWidget.checker_completed): Revert to
                                                         using
                                                         original API
                                                         with wait(2)
                                                         condition
                                                         value.
