Summary:
Currently, Hadrian has restrictive upper bounds on
`containers` and `QuickCheck` that prevents it from building with
the latest versions of each respective library (0.6.0.1 and
2.12.6.1). There doesn't appear to be any good reason to do so,
since Hadrian builds fine with them, so let's bump the upper version
bounds accordingly.

Test Plan: ./build/hadrian.sh
