mingw: changes to handling of directory permissions

The read-only attribute on a directory in Microsoft Windows is
quite different from write permission in POSIX.  Modify rmdir(2)
and chmod(2) to provide more POSIX-like behaviour:

  rmdir will remove a directory even if it's read-only
  chmod won't make a directory read-only
