hooks/post-install/prepare-32bit: fix rdep conversion with subpkgs.

If a required dependency is a subpackage and it does not contain shlib-provides,
do not convert to 32bit.

This fixes the issue of gtk+-32bit requiring gtk-update-icon-cache-32bit,
which was simply wrong because the latter does not provide any shlib.
gtk+: rebuild to generate proper 32bit pkgs.
cabal-install: update to 1.20.0.3.
