fix: specify FVP start ports explicitly

This change ensures that every supported FVP is explicit about the ports
that it will try to bind to. This is a mitigation against the
sometimes-random order in which terminals are enumerated by the various
FVPs, which causes our LAVA tests to attempt to read from the wrong
terminal.
