nova: Fix RunServer userdata encoding

According to the go docs, []byte fields are automatically serialized as
base64 encoded strings, so no need to do it twice (and post-bootstrap
fails due to this).

So, this is fine in general as an alternative to Ian's fix of using string
rather than []byte as the type.

The issue is we lack a test to catch the problem, which is one reason we spent
so long confused this morning. :)
