haskell.packages.ghc865Binary: drop unevaluatable packages

`haskell.packages.ghc865Binary` has a few packages that fails to evaluate
by referring non-existent attributes. This turns evaluation attempts into
unrecoverable errors.

Before the change an attempt to instantiate all `ghc810` packages failed
as:

    $ nix-instantiate --strict --eval --expr 'with import ./. {}; lib.mapAttrs (n: v: builtins.tryEval (lib.isDerivation v)) haskell.packages.ghc865Binary'
    error:
       … while evaluating the attribute 'llvmPackages'

         at lib/attrsets.nix:1180:11:

         1179|     attrs:
         1180|     attrs // { recurseForDerivations = false; };
             |           ^
         1181|

       error: value is null while a set was expected

The change follows definition of `pkgs/top-level/haskell-packages.nix`
and also sets `llvmPackages` to `null`. While at it dropped other
references to deleted packages like `exceptions` pin.
