Vincent Ambo 3652326ed2 refactor(3p/nix): Anchor local includes at src/
Previously all includes were anchored in one global mess of header
files. This moves the includes into filesystem "namespaces" (if you
will) for each sub-package of Nix.

Note: This commit does not introduce the relevant build system changes.
