Replace deprecated readdir_r with readdir

readdir_r is deprecated and should be replaced with readdir. readdir_r
is considered unsafe on systems where NAME_MAX is undefined and on
some systems it cannot read directory entries with very long names.

Fixes build warning:
topology.c:357:2: warning: ‘readdir_r’ is deprecated
  [-Wdeprecated-declarations]
  while (!readdir_r(dir, &dirent, &direntp)) {
  ^~~~~
