difftool: prepare "diff" cmdline in cmd_difftool()
We call into either run_dir_diff() or run_file_diff(), each of which
sets up a child argv starting with "diff" and some hard-coded options
(depending on which mode we're using). Let's extract that logic into the
caller, which will make it easier to modify the options for cases which
affect both functions.
