Add mkGoEnv function
This creates an `mkGoEnv` function which takes care of adding the correct Go package to your development environment and installs development dependencies from tools.go in a Nix derivation. The "normal" workflow around Go with tools.go just sticks development dependencies in $GOBIN which isn't ideal since you have no separation between projects.
