[tldistro] Minor dependency suggestion

[pcpa at mandriva.com.br]

  Hi,

  I suggest collection-latexextra to explicitly require
collection-latexrecommended.

  I did a minor patch to handle this special case in my
new rpm packages, so that the "Provides: tetex-latex" in
"texlive-collection-latexextra" keeps old packages with
tetex-latex buildrequires working.

Thanks,
Paulo
