profiles/common: Force rebuilding GHC+packages.
I was glad that the issues because of the longstanding GHC determinism bug (https://ghc.haskell.org/trac/ghc/ticket/4012) happened less frequently with GHC 7.10. Unfortunately, they still happen, as reported by @Profpatsch at headcounter/deployment#19 so we're going to override the GHC derivation with an additional attribute that is exported into the environment of the builder. This attribute causes GHC and all dependant packages to be rebuilt on the Headcounter Hydra. The original issue was because we're using the official NixOS binary cache as well as building everything from source. It's helpful for not needing to rebuild the entire world, but for Haskell packages it's harmful until the mentioned GHC bug has been fixed. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
