e58dde1be0 eval.nix: Don't override modulesPath
`eval-config.nix` will set the canonical path for us that will then be used
to strip the module path prefixes in `nixos/modules/misc/documentation.nix` [1].
This should fix split docs build problems described in #50.

eval.nix: expose nixosModules.deploymentOptions (#49)
Allow flake users to import .#nixosModules.deploymentOptions
into their flake, so that the same expression can be used for both,
.#colmena.$host as well as .#nixosConfiguration.$host, without the
latter complaining about undefined options in "deployment".

7b69946d98 Ensure key ownerships are set correctly
Depending on when keys are uploaded (`deployment.keys.<name>.uploadAt`):

`pre-activation`:
We set the ownerships in the uploader script opportunistically and
continue if the user/group does not exist. Then, in the activation
script, we set the ownerships of all pre-activation keys.

`post-activation`:
We set the ownerships in the uploader script and fail if the
user/group does not exist.

The ownerships will be correct regardless of which mode is in use.

Fixes #23. Also a more complete solution to #10.
