trace_writer_impl: Pack length field in FinishTracePacket()

This applies the same optimization done in 6e516e800c31("protozero: Pack
length fields for short nested messages") to FinishTracePacket().

`FinishTracePacket()` is an alternative to
`protozero::Message::Finalize()` that's only used by the C shared_lib
API.

Future commits might reuse this code also for the C++ SDK, which already
has the optimization in `protozero::Message::Finalize()`.
