[PATCH] diagnostics: only MinGW 10.0.0 and later ships afunix.h

[Torbjörn SVENSSON]

Without this change, building with MinGW v9.0.0 or earlier gives the follwing 
error:

gcc/diagnostics/sarif-sink.cc:23:10: fatal error: afunix.h: No such file or 
directory
 #include <afunix.h>
          ^~~~~~~~~~
compilation terminated.
Makefile:1219: recipe for target 'diagnostics/sarif-sink.o' failed
make[1]: *** [diagnostics/sarif-sink.o] Error 1


Ok for trunk?

afunix.h was first included in MinGW 10.0.0.  For earlier versions, fall
back to internal definition.

gcc/ChangeLog:

        * diagnostics/sarif-sink.cc: Conditionally include afunix.h
          depending on MinGW version used.
