gpg,w32: Fix gnupg_remove.

Browse source 
* common/sysutils.c (map_w32_to_errno): New.
(gnupg_w32_set_errno): New.
(gnupg_remove) [w32]: Set ERRNO
--

To support Unicode gnupg_remove was changed to use DeleteFileW and not
properly tested because the code was alreadt used in Windows CE.
However, ERRNO was not set and thus Dirmngr failed due to

 if (!gnupg_remove (fname))
   log_info (_("removed stale te[...] file '%s'\n"), fname);
 else if (errno != ENOENT)
   {
     err = gpg_error_from_syserror ();
     log_error (_("problem remov[...] file '%s': %s\n"),
                fname, gpg_strerror (err));
     goto leave;
   }
