check: Use g_thread_yield instead of g_usleep(1)

Since the commit
https://gitlab.gnome.org/GNOME/glib/-/commit/01c02ac08b682de622930b1278c9c14d0ffe6c49,
g_usleep(1) will be translated to Sleep(1) on Windows which means
sleep in 1 millisecond. But GLib provides g_thread_yield() API
which is exactly what we required here for thread context switching.
