Removed excessive _seekdir() call in closedir(). This saves one lseek()

syscall.  Before r5958, seekdir() was called for its side effect of
freeing memory allocated by opendir() for rewinddir(), but that revision
added _reclaim_telldir() that frees all memory allocated by telldir()
calls, making this call redundant.

This introduces a slight change.  If an application duplicated the descriptor
obtained through dirfd(), it can no longer rely on file position to be
reset to the start of file after a call to closedir().  It's believed to
be safe because neither POSIX, nor any other OS I've tested (NetBSD, Linux,
OS X) rewind the file offset pointer on closedir().
