Make nix-shells functional

So one issue remaining is that nix-shell does not provides all required dependencies of the project.
This is due to this four lines:

https://github.com/input-output-hk/cardano-node/blob/nix-shell-fixes/default.nix#L49-L52

when commenting one (eg. ps.ouroboros-network), then we do get ouroboros-network:

$ nix-shell --run "ghc-pkg list | grep ouroboros-network-0"
WARNING: there are broken packages.  Run 'ghc-pkg check' for more details.
    ouroboros-network-0.1.0.0

but then nix-shell --run "cabal new-build all" result in:

trace: Using index-state: 2020-01-31T00:00:00Z for cardano-node
trace: WARNING: license "GPL-2.0-or-later" not found
Warning: No remote package servers have been specified. Usually you would have
one specified in the config file.
Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: ouroboros-network-0.1.0.0 (user goal)
[__1] unknown package: splitmix (dependency of ouroboros-network)
[__1] fail (backjumping, conflict set: ouroboros-network, splitmix)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: ouroboros-network, splitmix

Also I believe we should have been able to remove the packages list in shellFor, but then I get

nix-shell
