Remove md5() call from isolation test for CLUSTER and TOAST

This test was failing because MD5 computations are not supported in
these environments.  This switches the test to rely on sha256() instead,
providing the same coverage while avoiding the failure.

Oversight in f57e214d1cbb.  Per buildfarm members gecko, molamola,
shikra and froghopper.
