Hackage distro data is out of date and no longer being updated

[juhp]

See haskell/hackage-server#921 and commercialhaskell/stackage#5963.

From my investigation of package versions it looks like:

• the Stackage distro data probably corresponds to https://www.stackage.org/nightly-2019-06-20, and

• the latest LTSHaskell distro data is for https://www.stackage.org/lts-13.30 (or earliest 13.28) .

(For some reason salak is out of sync for both of them.)

I remember investigating this earlier (probably last year), but I couldn't see anything wrong with the Bytestring.

I thought we had a issue open earlier but seems not - also slightly sad that noone reported this earlier.
I believe I was already aware of the issue before 22 July 2019, when I mentioned it to other Stackage team members.

This was fixed in commercialhaskell/curator#24.
