[Libguestfs] [libnbd PATCH v4 3/4] generator: Rename states-reply-structured to states-reply-chunk

Upcoming patches to add extended headers want to share the common
payload parser with structured replies. Renaming the file and the
associated states from "structured" to "chunk" makes it more obvious
that we will be sharing the code independent from the header style
parsed in the earlier REPLY portion of the state machine.
