Fix AIX build break in gcc/diagnostics/sarif-sink.cc.

In AIX, build fails while trying to compile gcc/diagnostics/sarif-sink.cc.
Here is the snapshot of the error we are getting.

In file included from /opt/freeware/src/packages/BUILD/gcc/gcc/system.h:46,
                 from /opt/freeware/src/packages/BUILD/gcc/gcc/diagnostics/sarif-sink.cc:34:
/opt/freeware/lib/gcc/powerpc-ibm-aix7.3.0.0/13/include-fixed/stdio.h:593:12: error: conflicting declaration of C function 'int fgetpos64(FILE*, fpos64_t*)'
  593 | extern int fgetpos64(FILE *, fpos64_t *);
      |            ^~~~~~~~~

This happens when we include sys/types.h before defining _LARGE_FILES.
We can see similar errors with this sample program.

#include <sys/types.h>
#define _LARGE_FILES 1
#include <stdio.h>
int main()
{
   return 0;
}

In gcc/diagnostics/sarif-sink.cc we are including config.h after #include <sys/un.h> which intern
 including sys/types.h and causing the conflicting errors.
Including config.h before including sys/un.h should solve this error.

The patch is to fix the build break on AIX.

gcc/ChangeLog:
	* diagnostics/sarif-sink.cc: Move config.h at the begining.
