Fix for BUG#4375: Windows specific directories are copied

 during replication.
 Modified my_dir(). Now this function skips hidden and system
 files which sometimes are created by Windows.
 NOTE. The fix is similar to the previuos one (05 July 2004)
 except for correct setting of the 'attrib' variable value
 (within the previous fix this variable was left uninitialized
 when my_dir() was called with My_flags & MY_WANT_STAT == 0).
