types: fix dagOf behaviour with mkIf
This makes definitions like

    home.activation.foo = mkIf false "bar"

work, where previously they would complain about
`home.activation.foobar.data` being used but not defined.

The crucial part is that we don't call `convertAllToDags` in
`dagOf.merge`, because we need to process `mkIf`/`mkMerge` properties
first. So we let `attrEquivalent.merge` do its job normally, but give
it a type `dagEntryOf` that does the conversion.

Ideally this shouldn't require so much boilerplate; I'd like to
implement something like

    types.changeInto dagContentType elemType dagEntryAnywhere

in Nixpkgs.
