system tests: new tests for run, exec

 - Issue #6735 : problem with multiple namespaces; confirms
   combinations of --userns=keep-id, --privileged, --user=XX

 - Issue #6829 : --userns=keep-id will add a /etc/passwd entry

 - Issue #6593 : podman exec, with --userns=keep-id, errors
   (test is currently skipped because issue remains live)

...and, addendum: add new helper function, remove_same_dev_warning.
Some CI systems issue a warning on podman run --privileged:

   WARNING: The same type, major and minor should not be used for multiple devices.

We already had special-case code to ignore than in the SELinux
test, but now we're seeing it in the new run tests I added, so
I've refactored the "ignore this warning" code and written
tests for the removal code.
