System tests: add :Z to volume mounts

selinux-policy-34.9-1.fc34 breaks a behavior we've relied on
since (at least) January 2020:

   - Revert "Add permission open to files_read_inherited_tmp_files()
     interface"

That's probably the correct thing to do, but it breaks our
existing tests. Solution: add ':Z' where needed.

Tested on Ed's laptop, which has the offending selinux-policy
as of 2021-05-31. Tests pass root and rootless. (I mention
this because tests will obviously pass in CI, which has a
much older selinux-policy).

Also: add a 'podman rmi' for cleanup in one test, to avoid
noise in test logs.

Fixes: #10522
