wildmatch test: remove redundant duplicate test

Remove a test line that's exactly the same as the preceding
line.

This was brought in in commit feabcc1 ("Integrate wildmatch to
git", 2012-10-15), these tests are originally copied from rsync.git,
but the duplicate line was never present there, so must have just
snuck in during integration with git by accident.
