blink: fix missing inputs.self in HM and NixOS modules (#644)

* home-manager: fix missing inputs.self

some options in nvf module uses inputs.self but it's not exposed in the
inputs we pass to home-manager module:

example flake.nix:

```
{
	inputs = { /* ... */ };
	outputs = {nixpkgs, ...}@inputs: {
		testing = {
			a = inputs.self             # valid
			b = inputs.self.inputs      # valid
			c = inputs.self.inputs.self # does not exist

			# prior to this change, inputs.self.inputs was passed to the hm
			# module, which lacks the self attr
			#
			# This change passes in the "top-level" inputs instead.
		};
	};
}
```

* nixos: fix missing inputs.self
