fix(argon2-threads): fix cmake flag to disable multithreading

[ni0ki]

Description

(This is a backport of antelle@c552be9)

Disable multi-threading when compiling Argon2 library. The existing compilation flags (-DARGON_JS) was wrong / unused, and should be replaced by -DARGON_NO_THREADS.

What for ?

Because of this wrong flag, the WASM code was spawning Web Workers to handle multi-threading.

• This was not bringing any performance improvements, confirmed locally. Also see Investigate possibility of re-enabling threads? antelle/argon2-browser#52)
• In the context of ServiceWorkers, no web workers can be spawned, resulting in a runtime error.

Maybe directly add a commit to increment the package.json version field ?
