Yet more fallout from #113616. :-/
Is it really a problem to use a pipe to apt-cache dumpavail for this? Sure,
it's somewhat slower than reading the available file, but it still takes
less than a second on a relatively modest system. It's not as if users will
run tasksel frequently.
This wouldn't be too hard to implement, but isn't it the wrong thing to have
apt overwrite dpkg's information without dpkg asking? If you want the
information from apt instead, it's pretty easy to ask apt for it.
