raylib: include pre-compiled CFFI extension in wheel (#35)

Build the CFFI Python extension (_raylib_cffi.so) during wheel build
instead of deferring to first import. This eliminates the need for
libgl-dev and libx11-dev on the target system.

- setup.py: run build.py after build.sh to compile CFFI extension
- pyproject.toml: include _raylib_cffi*.so in package-data, bump to 5.5.0.3
- _shim_setup.py: extract .so files from wheel alongside data directory
