runtime(netrw): expand $COMSPEC without applying 'wildignore' (vim/vim#13542)
When expanding $COMSPEC and a user has set :set wildignore=*.exe
netrw won't be able to properly cmd.exe, because it does not ignore the
wildignore setting.
So let's explicitly use expand() without applying the 'wildignore' and
'suffixes' settings to the result
