Bug 1438557

Description of problem:
In RHEL Atomic Host 7.3.3 RUN_DIRECTORY could be set on the command line when installing a system container.  In 7.3.4, the RUN_DIRECTORY that is set is no longer applied and set to /run.

Version-Release number of selected component (if applicable):
7.3.4

How reproducible:
Always

Steps to Reproduce:
1. atomic install --system --name=hello-world  --set=RUN_DIRECTORY=/root gscrivano/hello-world
2. cat /var/lib/containers/atomic/hello-world/info
3. Verify that the RUN_DIRECTORY is not set to /root

Actual results:
RUN_DIRECTORY is set to /run

Expected results:
RUN_DIRECTORY is set to /root
