haskellPackages.hnix-store-{core,remote}: restrict to < 0.7

These are the only versions of these packages that are compatible with
hnix 0.17.0, pending haskell-nix/hnix#1112.
Since hnix has more reverse dependencies, it is easier to make its
requirements the default. Since Stackage LTS no longer tracks hnix-store-*,
the overridding situation is less hairy than it used to.

All hnix-store-* packages except hnix-store-core and hnix-store-remote
have been introduced after hnix-store-core >= 0.8 and need to be overridden
to use that.

This partially reverts commit  330ee35.
