Test if diff is present. This is needed on Windows systems
as the OS returns 1 whether diff is successful or if it is
not present.
We run diff -v and look for output in stdout.
We don't redirect stderr to stdout to make for a simplified check
Windows will output '"diff"' is not recognized... to stderr if it is
not present.
