Without this patch, building coreutils with
--enable-gcc-checking=expensive would fail with a message like
“lib/exclude.c:682:6: error: leak of FILE 'in' [CWE-775]
[-Werror=analyzer-file-leak]”, because Gnulib replaced fclose but
not fopen, and GCC saw a call to fopen followed by a call to
rpl_fclo
