wasm cerbero: Download and extract emsdk-3.1.58 (preliminary version)

Using the command:

    ./cerbero-uninstalled --config ./config/cross-emscripten-wasm.cbc bootstrap --system=no

Downloaded and extracted:

    ~/.cache/cerbero-sources/emsdk-3.1.58.tar.gz (bundle)
    ~/github/cerbero/build/emsdk-3.1.58 (extracted folder)

But still problems with:

    run_until_complete(bootstrapper.start(jobs=args.jobs))
  File "/home/jenkins/github/cerbero/cerbero/utils/__init__.py", line 769, in run_until_complete
