Bin Liu c83e6c7ed9 coroparse: Use readdir instead of readdir_r 
readdir_r is deprecated in glibc 2.24 in favor of readdir (which became
thread safe). Also because corosync never calls read_uidgid_files_into_icmap
in muliple threads, no problem should appears even with libc where
readdir is thread-safe.
