chef-workstation support for aarch64 linux

[harvimt]

Describe the Enhancement:

We want to run our test-kitchen tests on rhel7-compatible linux aarch64 based test runners which currently use the chef-workstation rpm for x86_64 using the kitchen-vagrant backend for test-kitchen and the vagrant-libvirt backend for vagrant.

Describe the Need:

A version of the chef-workstation rpm for the aarch64 architecture.

Current Alternative

Install ruby, test-kitchen, inspec, gems etc. into their own bundle on the test runners.

Can We Help You Implement This?:

We've attempted to run the chef-workstation rpm build on aarch64, and received build errors. If it's possible to build the rpm ourselves with a workaround that is acceptable.
