[tex-live] Bug#771078: texlive-latex-recommended: fontspec-luatex depends on eu2enc.def in texlive-xetex

[Karl Berry]

    - move euenc to collection-latexrecommended

It's tiny, so ok.  Also makes sense, in that if fontspec+luatex wants to
read it, it is not xetex only.

By the way, there is no fontspec-luatex package in TeX Live.
But I get the drift.

    - make collection-luatex depend on collection-xetex

Certainly not, for many reasons!
