Get rid of the dependency to GNU diff in the tests

Now that "git diff" handles stdin and relative paths outside the
working tree correctly, we can convert all instances of "diff -u"
to "git diff".

This commit is really the result of

$ perl -pi.bak -e 's/diff -u/git diff/' $(git grep -l "diff -u" t/)
