[tldistro] update for https://www.tug.org/texlive/distro.html

[Karl Berry]

Hi Jonas,

Thanks for the info.

    https://packages.gentoo.org/packages/app-text/texlive

Ok.  Should this replace https://wiki.gentoo.org/wiki/Project:TeX, or be
in addition to?

And, is Alexis Ballier still the right name, or should it be (e.g.) you?

    Gentoo: emerge dev-perl/Tk

Changed.

Thanks,
Karl
