Don't show transporter launch button in skirmish/multiplayer

[aco4]

This can occur when a mod spawns a transporter like so:

hackNetOff();
addDroid(player, x, y, "Transporter", "SuperTransportBody", "V-Tol", "", "", "NULL-VTOL-Transport-Turret");
hackNetOn();

... because hackNetOff() temporarily sets bMultiPlayer = false

Tested fixed on Windows 11

Interestingly, this also unintentionally fixes #4974

I'm investigating if

hackNetOff();
addDroid(player, x, y, "Transporter", "SuperTransportBody", "V-Tol", "", "", "NULL-VTOL-Transport-Turret");
hackNetOn();

... is the right pattern in the first place. Perhaps it should be:

addDroid(player, x, y, "Transporter", "SuperTransportBody", "V-Tol", "", "", "NULL-VTOL-Transport-Turret");

... with no hackNet?

It seems like addDroid() works without being wrapped in hackNet. But I'm not 100% certain because I believe it caused a bug previously? aco4/WZmodSurvival@6907198
