fix: address PR #31 and #32 review findings

- Dockerfile: fix LLVM apt repo codename (jammy → noble) for ubuntu:24.04
- build-linux.sh: add missing mkdir -p /wowee-build-src before tar extraction
- Dockerfile: remove dead ENV OSXCROSS_VERSION=1.5 and its unset
- CMakeLists: scope -undefined dynamic_lookup to wowee target only
- GameServices: remove redundant game:: qualifier inside namespace game
- application.cpp: zero out gameServices_ after gameHandler reset in shutdown
