pkgs-lib/tests/formats: improve message on failure
Foremost, the message was discarding double quotes on one side of the
diff, which was super-confusing to me, as I thought that the format
convertor broke that when in fact only whitespace was changed.

I thought I'd cat the files, but then... switching to `diff -u` seemed
self-sufficient.  It felt sufficiently non-controversial to push
directly, but certainly feel free to improve further.
