close: use gl_REPLACE_FCLOSE only if defined

* m4/close.m4 (gl_REPLACE_CLOSE): Use gl_REPLACE_FCLOSE only if it
is defined.  The close module doesn't depend on the fclose module
any more, so gl_REPLACE_CLOSE's existence cannot be assumed.  See
<http://lists.gnu.org/archive/html/bug-gnulib/2011-07/msg00392.html>.
I reproduced the problem with "./gnulib-tool --test close sys_socket".
