[PATCH] import: hackage: default to https urls.

[ng0]

This patch updates the hackage importer so that `guix import hackage
name' writes out a package definition which includes
https://hackage.haskell.org by default. The home-page field was not
fixed, but this is less important than the download.
I know that tls/ssl itself has a problem, but some people can't just use
tor, so the default should be to use tls when available at the source.

Imported Adaptive with this from hackage. It is a broken build (fails
with errors which are in the build process, not within the package
definition), the download succeeds. I have no idea about haskell, this
is just to proof that it works, the hello-world kind of package.
If someone wants to fix this package or tell me how this can be fixed,
you are welcome to do so.
