[JENKINS-36802] Unit tests using Docker Pipeline on OS X don't work

Trying to run unit tests that run Docker Pipeline on OS X with Docker for Mac, I get errors like:

java.io.IOException: Failed to run image 'httpd:2.4.12'. Error: docker: Error response from daemon: Mounts denied: he system.

You can configure shared paths from Docker -> Preferences...

.

0948921938454756test/workspace/p and /var/folders/pr/24nv8g910wg8vr4b4c33q34r0000gn/T/hudson4310948921938454756test/workspace/p@​tmp

are not shared from OS X and do not belong to t.

Wonderful error message, that. =)

The specific problem seems to be that since /var is a symlink to /private/var and both /private and / are set up in the Docker for Mac preferences to allow file sharing, /var still isn't allowed. This is...annoying.
