Build libgpiod into Python module for build_ext or bdist_wheel. Include libgpiod source in sdist so that the Python module can be built from source by end users, even with a missing or mismatched system libgpiod. Add optional environment variable "LINK_SYSTEM_LIBGPIOD=1" to generate a module via build_ext or bdist_wheel that links against system libgpiod. Update build to pass "GPIOD_VERSION_STR" as an environment variable when calling setup.py. This is saved to "gpiod-version-str.txt" and included in the sdist for standalone builds. The old make/make install behaviour is preserved by supplying "LINK_SYSTEM_LIBGPIOD=1" and an additional sdist package is built and saved into dist/ for upload to pypi.
