Exclude decode_to_md5 test from examples.sh.

Running this test in Jenkins causes all but trivial changesets to
fail unless the hash is changed. Other changes in master
can meanwhile cause the hash to be out of date by the time
of merge even if it is changed, so rebases of previously
passing changesets will then fail again.
