system tests: podman-remote, image tree

- new sanity checks for podman-remote:
  - first, confirm that when PODMAN is "-remote",
    we actually talk to a server (validated by
    presence of "Server:" string in "podman version").
  - second, add test for #7212, in which we run
    "podman --remote" (podman with --remote flag,
    not podman-remote command) and make sure --remote
    is allowed both as the first option and also
    with other flag options preceding.

- new test for "podman image tree" (piggybacking on
  top of a "podman build" test, because that gives
  us lots of layers).

- skip "podman exec - basic test" when remote. It is consistently
  causing CI failures, breaking all of CI, due to #7241.
