haskellPackages.chatter: unbreak

chatter's latest hackage release still depends on regex-tdfa-text, but
we can apply a patch from master to remove that dependency and jailbreak
to relax the bounds on cereal. Both these issues are already resolved
on master, so the override should only stand until the next release
comes around.

Additionally the test suite needs disabling as it doesn't list all
required modules in other-modules and thus fails to compile. The issue
has been reported upstream.

haskellPackages.fullstop: unbreak

Unfortunately fullstop is practically unmaintained and has no issue
tracker. The build failure is fortunately only affecting the test suite,
so a dontCheck resolves the issue for now.
