The latest kernels no longer define AUTOCONF_INCLUDED which was
being used to detect the new style autoconf.h kernel configure
options. This results in the CONFIG_* checks always failing
incorrectly for newer kernels.
The fix for this is a simplification of the testing method.
Rather than attempting to explicitly include to renamed config
header. It is simpler to unconditionally include <linux/module.h>
which must pick up the correctly named header.
