Subject: gnu: python-matplotlib-documentation: Fix build.

* gnu/packages/python-xyz.scm (python-matplotlib-documentation)
[native-inputs]: Add python-ipykernel; replace texlive with a texlive-union
consisting of texlive-latex-amsfonts, texlive-latex-amsmath,
texlive-latex-enumitem, texlive-latex-expdlist, texlive-latex-preview,
texlive-latex-type1cm, texlive-latex-ucs, texlive-generic-pdftex,
texlive-fonts-amsfonts, texlive-fonts-ec, texlive-fonts-adobe-times, and
texlive-fonts-txfonts.
[arguments]: Do not build PDF, remove PDF-related changes; patch to avoid
dependency on network resources.
