kbuild: Use inttypes.h when stdint.h are not available

The following is from Jean-Christophe Dubois <jdubois@mc.com>.
On Solaris 2.8, <stdint.h> does not exist, but <inttypes.h> does.
However, on Cygwin (the other odd place that the kernel is compiled
on) <inttypes.h> doesn't exist.  So we end up testing for __sun__ and
using <inttypes.h> there, and <stdint.h> everywhere else.
