Fix problem with _GL_JUST_INCLUDE_SYSTEM_INTTYPES_H on VMS.

* lib/stdint.in.h (_GL_JUST_INCLUDE_SYSTEM_INTTYPES_H): Define
before any system include files, and undef after them all.  This
should fix a problem on VMS reported by John E. Malmberg in
<http://lists.gnu.org/archive/html/bug-gnulib/2007-12/msg00118.html>.
