[bug#49779] [PATCH core-updates-frozen] gnu: texlive-latex-base: Propagate ‘texlive-latex-l3backend’

[Thiago Jung Bauermann]

Some packages need files from ‘texlive-latex-l3backend’ – which is a
supporting package of LaTeX3 – so propagate it from ‘texlive-latex-base’.

* gnu/packages/statistics.scm (r-with-tests)[native-inputs]: Remove
‘texlive-latex-l3backend’ from the texlive union.
* gnu/packages/tex.scm (texlive-latex-base)[propagated-inputs]: Add
‘texlive-latex-l3backend’.
(texlive-latex-xkeyval)[native-inputs]: Remove ‘texlive-latex-l3backend’.
