Previously, the ‘hackage-package?’ predicate was used which meant that
the updater would try to update non-Stackage packages, and lead to messages
like these:

  $ guix refresh -t stackage
  warning: failed to parse https://hackage.haskell.org/package/hurl/hurl.cabal
  warning: failed to parse https://hackage.haskell.org/package/idris/idris.cabal

Since ‘hurl’ and ‘idris’ aren’t available on the current Stackage LTS release,
they should be filtered out before the Stackage updater even tries to update
them.

* stackage.scm (stackage-package?): New procedure.
(%stackage-updater): Use it.
---
Changes since v1:

* Use ‘stackage-lts-info-fetch’ to improve performance.

Hi,

for some reason I cannot get this patch to apply. `git am` fails and also
`patch -Np1` spits out an error:

Can you push it somewhere?

Thanks,
Lars
