Ed Santiago e0bc8ffb59 Gating tests: diff test: workaround for RHEL8 failure
RHEL8 rootless gating tests are inconsistently failing with:

   $ podman diff --format json -l
   #
   {"changed":["/etc"],"added":["/sys/fs","/sys/fs/cgroup","/pMOm1Q0fnN"],"deleted":["/etc/services"]}
   # #/vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
   # #|     FAIL: added
   # #| expected: '/pMOm1Q0fnN'
   # #|   actual: '/sys/fs'
   # #|         > '/sys/fs/cgroup'
   # #|         > '/pMOm1Q0fnN'
   # #\^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Reason: PR #8561, I think (something to do with /sys on RHEL).

Workaround: ignore '/sys/fs' in diffs.
