    test-utils: Save Apache server root during initialization
    
    By the time we want to use it during teardown, it is no longer safe to
    call g_test_build_filename(), because some GTest state is discarded
    at the end of g_test_run() (see glib#2563). As a result, the command
    that should shut down the server fails, the server continues to run, and
    its port is unavailable for the next test-case.
    
    This should mostly resolve
    <https://gitlab.gnome.org/GNOME/libsoup/-/issues/175>.
