fix(3p/haskellPackages): re-add random 1.2.0 to fix xanthous r/2479

The random_1_2_0 attribute of haskellPackages currently holds random
1.2.0 which is what we want to have. We need to disable tests because
they cause an infinite recursion as basically all testing libraries
depend on random. This has the nice side effect that we no longer need
import from derivation for random 1.2.0 (but owothia and xanthous still
use it).

Re-enable CI for xanthous.

Additinonally we need to deal with the fallout of the haskellPackages
overlay now also being pulled in for some machines since cl/2910 and
let pandoc compile with random 1.2.0.
