testutils: Defer global cleanup until we really exit

Browse Source 
Some test suites try to call g_test_build_filename() after g_test_run()
has returned. In the installed-tests use-case where G_TEST_BUILDDIR and
G_TEST_SRCDIR are unset, that call uses test_argv0_dirname, which
is freed in test_cleanup(). Defer test_cleanup() using atexit() so it
isn't freed until after we return from main().
