make staging not working on macOS

[redshiftzero]

Description

I was running through the docs added in #3835, and discovered that the make staging target doesn't currently work as intended on macOS.

Btw we shouldn't remove the Vagrantfile in #3208 until we've tested the new makefile targets on both macOS and Linux (generally people are testing on the latter but not the former).

Steps to Reproduce

1. Check out latest develop
2. make build-debs
3. make staging

Expected Behavior

Staging machines are provisioned without issue

Actual Behavior

Note that the provider is correct (virtualbox-staging) here
