coreutils stat port to Solaris 9

[Paul Eggert]

Building coreutils CVS on Solaris 9 had this problem:

cc -xarch=v9 -DHAVE_CONFIG_H -I. -I. -I..  -I.. -I. -I../lib -I../lib    -g -c 
stat.c
"stat.c", line 563: warning: implicit function declaration: statfs

It turns out that the code was incorrect: it was calling statfs, but
on Solaris 9 you're supposed to call statvfs instead.  (lib/fsusage.c
gets it right.)  I installed this patch.

        * src/stat.c (STATFS): New macro, for portability to Solaris 9.
        (do_statfs): Use it.
