[Bug-gnulib] fchown-stub.c addition to gnulib

[Paul Eggert]

The CVS version of GNU Tar wouldn't build because the latest
gl_PREREQ_CHOWN does a AC_LIBOBJ(fchown-stub) but there was no
lib/fchown-stub.c in gnulib.  I installed the following obvious
patch to migrate coreutils's fchown-stub.c into gnulib.
