podman machine info: 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.
