chore(3p/haskell_overlay): remove obsolete overrides

I actually wanted to check up on regex-tdfa-text in owothia, but
realized it was actually in a dependency. When porting the patch for
chatter to nixpkgs, I wondered if we could get rid of other overrides
or if we need to fix anything else in upstream.

* aeson, attoparsec, cassava, psqueues, hedgehog: jailbreaks are
  no longer necessary

* fgl, fgl-arbitrary: upstream has the versions pinned by now

* hgeometry, hgeometry-combinatoral: upstream has moved past the
  pinned versions, but we don't need to keep them downgraded as
  xanthous's build is not broken by them.

* random-source: the upstream compiler shouldn't crash anymore,
  additionally upstream has the version pinned here currently

* semialign: upstream also has 1.1.0.1 by now

* splitmix: splitmix has been fixed upstream and haskellPackages
  has moved past 0.1

* hspec-core: test suite passes or upstream has disabled it as well

* QuickCheck: upstream advanced to the same version

* vinyl: upstream moved past the pinned version, causes no build failures

* comonad-extras: has been fixed upstream
