gitit: drop reference prevention code

All these references would (indirectly) incur a GHC requisite which is
prevented by #304352 via justStaticExecutables. Consequently, we can
stop setting disallowedReferences.

As it turns out the references we were removing aren't currently
created, so our life gets even easier.
