Previously embedded libcheck versions did not depend on (u)intmax_t and doing so would require projects using GStreamer's check framework to add AX_CREATE_STDINT_H to their configure.ac. A workaround is to fallback to glib types. This patch assumes that glib.h is always included before internal-check.h which is ok since everything Gstreamer would include gst/gstcheck.h instead of directly including internal-check.h. Fixes https://bugzilla.gnome.org/show_bug.cgi?id=727826
