difftool: Allow specifying unconfigured commands with --extcmd
git-difftool requires difftool.<tool>.cmd configuration even when
tools use the standard "$diffcmd $from $to" form. This teaches
git-difftool to run these tools in lieu of configuration by
allowing the command to be specified on the command line.
