netkit-telnet: Add a telnet package...

    telnetd does not compile with the debian patch, telnet compiles
    let us use that. This is not using update-alternatives as I think
    it is not necessary as this is the only telnet provider we have.

    The "buildsystem" is horrible... kick the configure to not run
    tests...
