Use readdir instead of readdir_r

Browse source 
* libguile/filesys.c:
* configure.ac: Remove readdir_r / readdir64_r checks and usage.
  glibc's impls are thread-safe, the _r variants are squirrely and now
  deprecated in glibc, and it is expected that POSIX will mandate that
  readdir{,64} be thread-safe already.  See
  https://sourceware.org/ml/libc-alpha/2016-02/msg00093.html.
