testsuite: fd-4.c redefines mode_t on AIX.

AIX stdio.h includes sys/types.h, which defines mode_t.  The
analyzer/fd-4.c testcase provides a definition of mode_t for creat()
call, which conflicts with the AIX definition.  This patch defines an
AIX macro to prevent multiple-definition of the type.

gcc/testsuite/ChangeLog:

	* gcc.dg/analyzer/fd-4.c: Define _MODE_T on AIX.
