Now that mbed tls has its own submodules, add `--recursive` to the
sample invocation of submodule update. Without this, building the
simulator produces difficult messages about `sha256.c` missing.

The README file is missing extra information about how to run all the
different test configurations; add this in.

Now that we depend on a submodule for mbed TLS code, update the docs to
explain how to fetch this. Otherwise, the error is somewhat misleading,
just showing a missing sha256.c file.
