Crypt Keeper 891761ac1e Adds support for FreeBSD (#671)
FreeBSD was disabled due to lack of testing. This works around the
compilation problems. Note: We can't currently test arm64 automatically!

Notes:

* GitHub Actions doesn’t support FreeBSD, and may never.
* We could use Travis to run FreeBSD, but it would split our CI config.
* Using Vagrant directly is easier to debug than vmactions/freebsd-vm.
* GitHub Actions only supports virtualization on MacOS.
* GitHub Actions removed vagrant from the image starting with macos-11.
* Since VirtualBox doesn't work on arm64, freebsd/arm64 is untestabl
