state: allow to unvendor cbor

This makes evolve fallback to an externally provided version of
the `cbor` library, which in turns allows distributions such as Debian
not to include the vendored `cbor.py` and rely on their own provided
version instead.

The price to pay is the immediate attempt to import the vendored `cbor`,
to circumvent that hgdemandimport never raises `ImportError` immediately.
