win32: treat devices as character special files

Commit 15fcbd19c (win32: special case for devices files in stat(2))
added special treatment in stat(2) for device files.

As a result of this change device files appeared to be regular files
which broke the use of /dev/null with noclobber in the shell.

Device files now appear as character special files (as they do on
Unix).

GitHub issue #225.
