using system tar on macOS to extract .pkg payloads

[shodiBoy1]

This PR fixes #796

Implemented changes:

• macOS .pkg files contain a Payload thats a gzipped cpio archive, but the old code tried to read it as gzipped tar
  every .pkg install crashed (e.g. AWS CLI on Mac).
• Switched the Payload extraction to macOS's system /usr/bin/tar (bsdtar), which handles gzip + cpio automatically.
