Installer command fails to install pkg in M1 macOS without Rosetta

[ningziwen]

Describe the bug Current aarch64 installer can't be installed by installer command in M1 macOS without Rosetta installed.

Steps to reproduce

1. Get a fresh M1 macOS host without Rosetta installed. (For example use macOS EC2: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-mac-instances.html)
2. Run /usr/bin/pgrep -q oahd && echo Yes || echo No to validate Rosetta is not installed. "No" means it is not installed.
3. Run sudo installer -pkg <aarch64 installer pkg path> -target /

Expected behavior Installation succeeds.
