Bug#966495: python-pyxs: please make the build reproducible

Hi,

Whilst working on the Reproducible Builds effort [0] I noticed that
python-pyxs could not be built reproducibly.

This is because the linkcode Sphinx extension and linkcode_resolve get
confused and try to link to the documentation to the @contextlib.contextmanager
decorator, and then uses relpath... All this results in links differing
depending on the number of directory components in the absolute build path:

  href="https://github.com/selectel/pyxs/tree/0.4.2-dev/pyxs/../../../../usr/lib/python3.8/contextlib.py#L25-L33

vs.

  href="https://github.com/selectel/pyxs/tree/0.4.2-dev/pyxs/../../../../../usr/lib/python3.8/contextlib.py#L25-L33"

As these links are broken anyway, I've attached a patch that will simply
hide them if we know they will be wrong. I think the right fix would be
to resolve the location of the exact function "underneath" the decorator.
