wireprotoframing: use our CBOR module

Tests changed because our CBOR encoder appears to sort map keys
differently from the vendored CBOR package. The CBOR specification
does define canonical sorting rules for keys based on the
byte values. I'm guessing our implementation doesn't follow them.

But our encoder doesn't guarantee that it conforms with the canonical
specification. Right now, we just care that output is deterministic.
And our encoder does guarantee that.
