Fix (remaining?) bugs for DIRECTORY.

Fixes Quicklisp, aka the "DIRECTORY no longer works with
:WILD-INFERIORS" problem, q.v. <​http://abcl.org/trac/ticket/344>.

DIRECTORY under non-Windows now fills nil DEVICE components with
:UNSPECIFIC, otherwise forms like

(equal (truename "~/.emacs")

(first (directory "~/.emacs")) )

fail (c.f. ANSI test DIRECTORY.[67]).

     103### DIRECTORY sets DEVICE to :UNSPECIFIC
     104
     105When the default for the :RESOLVE-SYMLINKS argument to DIRECTORY was
     106changed to nil, DIRECTORY was changed not to always resolve its
     107results via TRUENAME.  As a result
     108
     109    (equal (truename "~/.emacs")
     110           (first (directory "~/.emacs")) )
     111
     112forms would return nil.  This is a bit counter to expectations set by
     113CLHS that DIRECTORY "returns a list of pathnames corresponding to the
     114truenames".  In particular, this breaks the ANSI CL DIRECTORY.[67]
     115tests.  Thus, under non-Windows we now explicitly normalize DEVICE
     116components which are nil to :UNSPECIFIC for the results of DIRECTORY
     117calls.
