The top level of CTF containers is a "CTF archive", which contains a
collection of named members (each a CTF dictionary). In the serialized
file format, this is optional and skipped if the archive would have only
one member, as when no ambiguous types are present: so it is commonplace
to have a simple ctf_dict_t written out, with no archive container
wrapped around it.
But, unlike ctf_archive_iter, ctf_archive_next didn't quite handle this
case right. It should set the name of this fake "member" to
_CTF_SECTION, i.e. ".ctf", but it was failing to do so, so callers got
an unintialized variable back instead and were understandably confused.
So set the name properly.
