import: stackage: Updater resolves inputs lazily. 

Fixes the "haskell-stackage" test in 'tests/lint.scm', which started
failing with e6223017d9 because the extra
HTTP GETs induced by the 'haskell-fetch' calls would fail.

* guix/import/stackage.scm (latest-lts-release): Call 'hackage-fetch'
and its continuation from within 'inputs', which is delayed.  Pass it
NAME-VERSION instead of HACKAGE-NAME-VERSION.
