Revert "skins: use readdir_r() instead of readdir()"

This reverts commit 4bf419574b51ced5dea893f9e247fe38a2a0d163.

This is not needed. readdir() uses one dirent buffer per DIR pointer,
not per process. In other words, as long as a given DIR pointer is used
in a single thread, readdir() is thread-safe.
