gnu: texlive-libkpathsea: Enforce ls-R usage by default.

Fixes: https://issues.guix.gnu.org/75893

* gnu/packages/tex.scm (texlive-libkpathsea): Set TEXMF so that ls-R database
is mandatory and must contain the file looked after in the TeX Live tree.
* guix/build/texlive-build-system.scm (configure-texmf): Relax requirements
for "ls-R" database.  Renamed from `set-texmfvar'.
(%standard-phases): Apply phase renaming.
* gnu/packages/python-xyz.scm (python-nbconvert)[native-inputs]: Add TeX Live
packages required for tests to pass since propagated packages are no longer
accessible during build.
* gnu/packages/books.scm (book-sparc)[inputs]: Move TeX Live related inputs
to...
[native-inputs]: ... here, and wrap them within texlive-local-tree for the
same reason as above.
