Sync for vehicle specific electrics

[DaddelZeit]

Vehicle specific electrics are used by smooth lights, lightbars, or other misc vehicle parts:

They are calculated per frame from electrics values set by outside Lua.

KissMP attempts to sync these like any electrics value, but they are overwritten by each client's real value immediately.
It should be fine to disable sync for these values entirely.
