Cygwin: reduce size of fhandler_cygdrive

Browse Source 
fhandler_cygdrive has a size of 696 bytes on x86_64, while the next
biggest fhandler type, fhandler_pty_master, is 584 bytes.  The members
responsible for the size are private to opendir/readdir/closedir usage.
fhandler_disk_file stores private readdir data in DIR->__d_internal
instead.  Use equivalent method with fhandler_cygdrive.  This drops
the size to 464 bytes.
