diff-highlight: mention build instructions
Once upon a time, this was just a script in a directory that could be run directly. That changed in 0c977dbc81 (diff-highlight: split code into module, 2017-06-15). Let's update the README to make it more clear that you need to run make. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
