pkgs/sandbox: Prepare for querying runtime paths

We're now using a makefile for building the sandbox and use pkg-config
to pass in the flags we need for compiling against lib(nix)store.

Right now the sandbox itself doesn't do anything different because we're
not actually using the (incomplete) code for querying the store.
