BATS tests - get working again

Various small fixes to get BATS tests working again.
Split from #2947 because that one keeps getting stalled,
and I'm hoping these separate changes get approved.

I consider these changes urgent because RHEL8 gating
tests are failing, and will fail even more if/when #2272
gets picked up and packaged for RHEL8, and I consider
it important to have clean passing tests for RHEL8.

  * info test: 'insecure registries' is gone. A recent
    commit (d1a7378aa) changed the format of 'podman info',
    removing the 'insecure registries' key. Deal with it.

  * info test: remove check for .host.{Conmon,OCIRuntime}.package;
    the value on f28 and f29 is 'Unknown' (instead of an NVR).
    We can live without this check.

  * 'load' test: skip when running in CI, because stdin
    is not a tty.

  * container restore: fix arg processing. #2272 broke argument
    processing: 'podman container restore', with no args, should
    exit with 'argument required' error. Root cause is that the
    new --import option takes the place of an argument, so the
    checkAllAndLatest() call had to be changed to not exit on error.
    Workaround is (sigh) to copy/paste the skipped checkAllAndLatest()
    code, with minor tweaks to accommodate --import.
