Update emscripten patches again (#2684)

This drops the Rust patch and "Throw away errors in minify wasm_js" which
I suspect was fixed by an emscripten update (I'm not sure how long ago). It 
replaces the two remaining emscripten patches with new versions that match
the versions I am upstreaming.

3.1.13
------
+3.2.0
+-----
+- Emscripten now knows what minimum browser versions the `WASM_BIGINT` feature
+ requires and will automatically set the defaults accordingly. (#17163)
+- Weak undefined symbols fixed in dynamic linking. (#17164)
+- Internally, the name of `main` function now gets mangled (by clang) in the
+ same way as with other wasm targets. This means that within the wasm module
+ the name of the main function can now be `__main_argc_argv`, but, since we
+ still export this to JS as `_main`, this should not be a user-visible change.
+- Use of pkg-config from cmake not longer causes the C++ include path to be
+ broken. (#17137)
+- `emscripten_runtime_keeplive_push()` and `emscripten_runtime_keeplive_push()`
+ are now exposed to native code and can be used to keep the runtime alive
+ without immediately unwinding the event loop (as
+ `emscripten_exit_with_live_runtime()` does). (#17160)
+- Added a shim for `BigInt64Array` so `-sWASM_BIGINT` can be used in Safari
+ v14. (#17103)
+
+3.1.13 - 06/02/2022
+-------------------
+- xlocale.h compatibility header was restored after being removed in 3.1.12.
