cfm: Cleanup output of ovs-appctl "cfm/show" command.

When no remote MPIDs were found, the output would print an extra newline.
If multiple remote MPIDs were found, the lines would run together.  This
commit cleans things up a bit by just printing each item on its own line
without any blank lines.
