t3701: verify that the diff.algorithm config setting is handled

Browse Source 
Without this patch, there is actually no test in Git's test suite that
covers the diff.algorithm feature. Let's add one.

We do this by passing a bogus value and then expecting `git diff-files`
to produce the appropriate error message.
