Fix include: with machineid-compat and a few other keys

Browse Source 
It turns out we basically have to slap an `Option<T>` around
everything, (in particular `bool` etc.) we need to be able
to distinguish in (I believe) all the cases between
"value unspecified" and "value provided".

Concretely it didn't work to try to set `machineid-compat: false`
in an included yaml treefile becuase it was just defaulted to `true`
by the toplevel.

Down the line we should move all of the parsing into Rust
and have two different `struct` types for "YAML we load" versus
"verified treefile".
