NS Linux mouse wheel issue

[jirikivaari]

Mouse wheel triggers mouse4 for some reason. Hopefully this is just a HL1 linux issue ant not a memory leak etc. Need to check further.

Only happens on Linux.

ADDEDNDUM:

I also cannot use +jump in mousewheel to bunnyhop.

There's some discussion about mouse wheel issues here that might be related:

Thanks.

Also I cannot use mouse wheel at all for jumping. It will throttle and break the speed.

This happens for hldm too so its not ns-specific. Probably related to SDL.

This can be fixed by linking the libSDL2.so to SDL 2.0.8 which is in latest ubuntu 18.04.

I think we have to ship it with the binaries. Not sure how to make sure its loaded first though instead of the SDL library in half-life directory.
