build_tests.py is not part of the sdist so tests cannot be built from
pypi releases. Add it to MANIFEST.in.

Optionally vendor libgpiod source into sdist so that the Python module can
be built from source, even with a missing or mismatched system libgpiod.
Add two new environment variables "LINK_SYSTEM_LIBGPIOD" and
"LIBGPIOD_VERSION" to control what kind of package setup.py will build.
In order to build an sdist or wheel package with a vendored libgpiod a
version must be specified via the "LIBGPIOD_VERSION" environment variable.
This will instruct setup.py to verify the given version against the list
in sha256sums.asc and ensure it meets or exceeds a LIBGPIOD_MINIMUM_VERSION
required for compatibility with the bindings.
It will then fetch the tarball matching the requested version from
mirrors.edge.kernel.org, verify the sha256 signature, unpack it, and copy
the lib and include directories into the package root so they can be
included in sdist or used to build a binary wheel.
eg: LIBGPIOD_VERSION=2.1.0 python3 setup.py sdist
Will build a source distribution with gpiod version 2.1.0 source included.
It will also save the gpiod version into "libgpiod-version.txt" so that it
can be passed to the build when the sdist is built by pip.
Requiring an explicit version ensures that the Python bindings - which
can be changed and versions independent of libgpiod - are built against a
stable libgpiod release.
In order to force a package with vendored gpiod source to link the system
libgpiod, the "LINK_SYSTEM_LIBGPIOD" environment variable can be used:
eg: LINK_SYSTEM_LIBGPIOD=1 pip install libgpiod

__main__.py and __init__.py are omitted with the default source discovery
so add an explicit recursive include for tests in order to package them.

We want to package the .c sources for test-specific extensions so add
them to the manifest.

In order to allow building sdist and wheel packages for python bindings
with python3-build, add a proper MANIFEST.in file.
