podman machine inspect: use report.Formatter over Template

Currently the podman command --format output code uses a mix of
report.Formatter and report.Template.

I patched report.Formatter to correctly handle newlines[1]. Since we
cannot fix this with report.Template we have to migrate all users to
report.Formatter. This ensures consistent behavior for all commands.

This change does not change the output, we can add a new test for the
newline bug when the common PR is vendored in.

Also fix a bug where a invlaid template would not cause a exit code > 0,
see the added test case.
