Commit f3206c3 split each FFI export into two distinctly-named Nim procs
(`<name>CborExport` / `<name>NativeExport`, and the ctor variants), so the
bare user name now resolves only to the Nim-native helper. The C-shape
integration tests still invoked the CBOR entry points by the bare name and
no longer compiled. Point those call sites at the `*CborExport` /
`*CborCtorExport` procs; the Nim-native `waitFor <name>(lib, ...)` calls keep
the bare name on purpose.
