Can't bootstrap archived versions on macOS

[pjcreath]

Description of Issue/Question

Since the -R flag is ignored for macOS, there's no way to make the bootstrap script deploy an archived version of salt.

This is a pressing issue, since the non-archived versions won't install on macOS older than 10.15.

PR coming momentarily.

Setup

macOS 10.13

Steps to Reproduce Issue

sudo sh bootstrap-salt.sh -R archive.repo.saltproject.io -D stable 3004
