Vehicle spawning fixes

[ohlidalp]

Fixes:

• https://forum.rigsofrods.org/resources/mercedes-benz-atego-1318-comax.344/ - some flexbodies were missing because truckfile parser was too strict on syntax. Restored to original.
• https://forum.rigsofrods.org/resources/c1-offshore.182/ - segfault due to missing simbuffer update when procesing 'wings'. Only hapenned for vehicles without 'flexbodies' or 'wheels'.

@tritonas00 Great, but got a new issue in master: airplanes segfault, like skyvan

Thanks for testing, and good catch! That segfault was actually introduced by this: https://github.com/RigsOfRods/rigs-of-rods/pull/2925#issuecomment-1320942624. Airplanes have a special 'spin prop' which doesn't get the mesh attached on spawn but only when the rotor reaches certain RPM.

Same crash with Fica 750 also

Might be a bad prop with missing mesh file, anything in RoR.log?

[tritonas00]

Can't tell: RoR.log

Again commenting that line (GUI_FlexbodyDebug.cpp:195) works. So it needs a check there probably.

It's a missing mesh file indeed:

I'll patch it.
