    run-tests.sh: Launch a mock org.gnome.SessionManager to control the lifetime of the daemons
    
    Both at-spi-bus-launcher and at-spi2-registryd will keep running
    indefinitely unless the session manager tells them that the session is
    ending.
    
    During the CI tests, the daemons are killed when the tests finish.
    They don't get a chance to exit cleanly.
    
    GCC's code coverage machinery from libgcc depends on a process exiting
    cleanly for it to be able to write out the .gcda files.  These files
    were never written for the a11y daemons because they didn't exit
    cleanly.
    
    This commit changes the test runner to launch a mock implementation of
    the org.gnome.SessionManager interface.  It does nothing but accept
    clients that register themselves, and to signal clients for session
    termination.
    
    The daemons now pick up that signal from the mock, as if it were from
    a real session, and exit cleanly.
