Subject: [PATCH] Linux: add launcher script to fix issue launching on Steam

The steam environment sets LD_LIBRARY_PATH with a libtbb.so.2 that is
incompatible with our own. This wrapper scripts gives our own library
priority.

There is a more modern "Steam Linux Runtime" that can be used instead of
the "LD_LIBRARY_PATH Steam Runtime" and which launches Blender, but it
fails to detect GPU compute libraries. So that was not an option.

Ref #107385
