Improve coverage speed for musl and free-threaded Pythons

PyPI has pre-built architecture-specific coverage wheels for Python >=
3.13 interpreters built with free threading support and Python >= 3.9
interpreters linked to musl. Include them in the coverage multi-arch
wheel so they benefit from native-speed tracing under `plz cover`.
