electron-builder: Built for arm64 on x64 doesn't mount

• Electron-Builder Version: 23.0.3
• Node Version: 16.4.2
• Electron Version: 19.0.1
• Electron Type (current, beta, nightly): current
• Target: darwin + arm64

The dmg file built for arm64 (with --arm64 option) does not open on M1 chip laptops. Possible reason is here packages/dmg-builder/src/dmg.ts#L202 since to enable APFS, it checks if current process is running on arm64, not the option we passed. Then on laptops with M1, hdiutil cannot mount HFS filesystems.
