gnu: texlive: Make the package structure more modular.

* gnu/packages/texlive.scm (texlive-bin, texlive-texmf): New variables.
  The first one contains the binaries; the second one the texmf tree.
  (texlive): Drop output "data". Create the output "out" as the union
  of the suitable subdirectories of texlive-bin and texlive-texmf, and
  wrap the binaries, setting TEXMFCNF to the value corresponding to
  texlive-texmf.
