It is literally impossible to get the name of a Worker's own script,
so impossible to derive X.wasm from script name X.js. Thus we need,
at build-time, to redifine Module['instantiateWasm'].uri by
appending it to a build-specific copy of this file with the name of
the wasm file. This is apparently why Emscripten hard-codes the name of
the wasm file into their glue scripts.
