t7003: fix subdirectory-filter test

The test would not fail if the filtering failed to do anything, since
in

  test -z "$(git diff HEAD directorymoved:newsubdir)"'

'directorymoved:newsubdir' is not valid, so git-diff fails without
printing anything on stdout.  But then the exit status of git-diff is
lost, whereas test -z "" succeeds.

Use 'git diff --exit-code' instead, which does the right thing and has
the added bonus of showing the differences if there are any.
