Prefer mtr-tiny over mtr on Debian

[tbaschak]

Since this is designed for a server-type operating system, installing mtr-tiny on Debian would prevent pulling in ~38 dependancies. This looks like it would require another fixup if loop in the setup script.

I'm not sure if packages on RHEL based systems have a similar option, or if theirs is similar to mtr-tiny to begin with.

Add network commands to configuration #13 could do this....
