kbuild: add checks for include of linux/types in userspace headers
If we see __[us](8|16|32|64) then we must include <linux/types.h> If wee see include of <asm/types.h> then we recommend <linux/types.h> Original script from Mike but modified by me. Cc: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
