[bug#74393] [PATCH v2 2/2] gnu: texinfo-7: Use external modules.

[gemmaro]

* gnu/packages/texinfo.scm (texinfo-7): Use external modules
rather than bundled ones.
[inputs]: Add perl-unicode-eastasianwidth, perl-text-unidecode,
and perl-libintl-perl.
[arguments]<#:configure-flags>: Add a phase
to enable the use of external modules.
<#:phases>: Add Perl modules to the PERL5LIB variable of the texi2any program
in the wrap-program phase.
