* Translate all seds in postPatch into patches (for setting the static
path and skipping the test that needs network access)
* The patch for the changed pandoc heading generation was simplified:
Since we know our pandoc version is always that new, we can skip the
version check.
* Skip the test for pandoc-citeproc: pandoc-citeproc has been deprecated
in favor of pandoc --citeproc by the upstream pandoc developer.
pypandoc's testsuite doesn't reflect this yet (although it should
support --citeproc theoretically) to avoid depending on
pandoc-citeproc for the checkPhase (as we expect it to break again or
continue to be broken) we skip the test requiring pandoc-citeproc.
The breakage of pypandoc due to pandoc-citeproc was pointed out here:

Thank you!
