refactor(ops/nixos): Pass `depot` as a special argument r/2626

This changes the evaluation order for the `depot` argument and ensures
it is partially evaluated before the module system starts resolving
imports.

This way we can import modules from `depot.path` without `depot`
having to come from readTree.

Fixes b/129.
