Feature request: add prebuilt libzim for Linux aarch64

[zhuowei]

On Fedora 35 for aarch64 (in VMWare Fusion on macOS Apple Silicon), installing node-libzim gives the error:

npm ERR! /usr/bin/ld: /home/zhuowei/mwoffliner/node_modules/@openzim/libzim/download/lib/x86_64-linux-gnu/libzim.so.6: error adding symbols: file in wrong format
npm ERR! collect2: error: ld returned 1 exit status

node-libzim should provide a prebuilt libzim for aarch64 or, if not possible, check for non-x86_64 linux and avoid using the built-in library.

This directly depends on kiwix/kiwix-build#528
