cargo wasm-pack install does not work on aarch64

[alphaqu]

🐛 Bug description

I want to install wasm-pack on my server which runs an arm64/aarch64 CPU. The installer does not work so I did cargo install wasm-pack. It compiles but when I run npm install -g wasm-pack or yarn global add wasm-pack it fails.

🤔 Expected Behavior

It registers to the system and does not crash npm.

👟 Steps to reproduce

• cargo install wasm-pack
• sudo npm install -g wasm-pack

/usr/bin/wasm-pack -> /usr/lib/node_modules/wasm-pack/run.js

> wasm-pack@0.10.2 postinstall /usr/lib/node_modules/wasm-pack
> node ./install.js

/usr/lib/node_modules/wasm-pack/binary.js:20
  throw new Error(`Unsupported platform: ${type} ${arch}`);
  ^

[omninonsense]

I'm not sure this issue will be resolved by #1122, since that PR fixes the the download one-liner script. This seems to be triggered by a JS error, so the download logic must be duplicated there.

I could port the same fix to JS as a part of the original MR (it would still be in the spirit of it), because this has come to bite me a second time.

Fixed in v0.11.0.
