[glib/wip/pwithnall/gdbus-names-livelock] tests: Port gdbus-names test entirely to GMainContext

[Philip Withnall <pwithnall src gnome org>]

commit 32e8e4ad91890b97fde924038743af7faa245f65
Author: Philip Withnall <pwithnall endlessos org>
Date:   Mon Jun 21 14:07:21 2021 +0100

    tests: Port gdbus-names test entirely to GMainContext
    
    It makes combination exit conditions a lot easier than when using
    `g_main_loop_quit()` from different callbacks.
