Refactor avm-server interface mod to new crate (#294)

* Refactor `avm-server` interface mod to new crate (#294)

The new crate name is `avm-interface`.

It allows to build fully native air-trace, including pure WASM build.

* Make fully native air-trace build

Unless `wasm` feature is enabled (default), fully native build is
produced.  You may build WASM air-trace binary with

`cargo build --target wasm32-wasi --no-default-features --release -p air-trace`

* Fix tracing output on native air-trace build

Wrong option was used.
