Fix bug #7308 with `locate' on MS-Windows.

dired.el (dired-get-filename): Replace backslashes with slashes
 in file names on MS-Windows, needed by `locate'.
 locate.el (locate-default-make-command-line): Don't consider
 drive letter and root directory part of
 `directory-listing-before-filename-regexp'.
 (locate-post-command-hook, locate-post-command-hook): New defcustoms.
