Avoid encoding file names run through dostounix_filename on MS-Windows.

 src/w32.c (normalize_filename): Accept an additional argument
 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
 downcase it even if w32-downcase-file-names is non-nil.

 pass it to normalize_filename.
 (emacs_root_dir): Adjust.
