Subject: [PATCH] Turn module into file path.

If a module is an attrset deduplicating imports does not work properly
and would lead to the module system complaining about redefining
options. Here is an example:

error: The option `age.identityPaths' in `/nix/store/wn50ysifrfp5qj5pp3jqpyvwh8ksz36y-source/machines/foo' is already declared in `/nix/store/wn50ysifrfp5qj5pp3jqpyvwh8ksz36y-source/common/ddclient/default.nix'.

when common/ddclient/default.nix and machines/foo/default.nix is:

{ ..., agenix, ... }: {
  imports = [
    agenix.nixosModules.age
  ];
}

Turning the module into a filepath fixes the issue.
