Reland "[wasm][test] Fix test expectation"

This is a reland of 6f9cde1e, with
special handling for MSan as well.

Original change's description:
> [wasm][test] Fix test expectation
>
> In the mprotect case, there could be one or multiple succeeding writes
> until we finally crash. Thus do not check that we never successfully
> write, but just check that the last printed statement is *before* a
> write.
