patch for gst-plugins-good

The function gst_matroskamux_pad_get_type is not thread safe.
If one thread is reading type and sees that it 0 and call g_type_register_static_simple but before write to type another thread is doing the same.

patch for gst-plugins-good

This should use g_once_init_enter()/_leave() as all the other type registration code... or ideally just use the G_DEFINE_TYPE() macro.
