Per https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/xbd_chap04.html: "A pathname that begins with two successive slashes may be interpreted in an implementation-defined manner, although more than two leading slashes shall be treated as a single slash." So more than 2 leading slashes are supposed to be folded into one, which our dirname neglected. Fix that. Fixes: 24e8fc6872a3b ("* cygwin.din (basename): Export.")
