awxfifo creation fails when write access to container is prohibited.

Steps to reproduce

• Apply security policy with "readOnlyRootFilesystem" context to Kubernetes cluster.
• Start AWX installation with AWX Operator.

Expected results

If the file was located in different directory or subdirectory of /var/lib/awx, then with help of awx-operator emptyDir can be mounted to such location. Thus allowing awxfifo file to be created.

---
spec:
...
  extra_volumes:
    - name: awx-fifo
       emptyDir: {}

task_extra_volume_mounts: |
   - name: awx-fifo
     mountPath: /var/lib/awx/fifo

master-fifo = /var/lib/awx/fifo/awxfifo

Actual results

uwsgi will prevent startup of web container due to inability of writing to /var/lib/awx directory.
