add very naive logic for launching in steam runtime

Browse source 
the logic added here is very naive and just copies the SDK 2013 mp lookup.
it then runs `$RUNTIME_DIR/_v2-entry-point -- hl2.sh` to ensure everything is setup right

`_v2-entry-point` is labeled as a prototype so this might break in the future

`$RUNTIME_DIR/run -- $RUNTIME_DIR/pressure-vessel/bin/steam-runtime-launcher-interface-0 container-runtime ./hl2.sh` might be better?
unsure

there are better ways of handling this in the code, this is mostly just to get things working without changing everything
