Description of problem:
When starting docker permissions change on /var/lib/docker and /etc/sysconfig/docker-storage, in turn causing OpenSCAP to warn about the permission change. 


Version-Release number of selected component (if applicable):
docker-1.12.6

How reproducible:
100%

Steps to Reproduce:
1. Install docker
2. Start docker

Actual results:
```
FINDING 1:

(HIGH) Verify and Correct File Permissions with R= PM (xccdf_org.ssgproject.conte= nt_rule_rpm_verify_permissions)

Items found violating = mode of all files matches local rpm database: 
```

Expected results:
No findings, rpm to ship with right permissions or permissions remain unchanged. 

Additional info:

Verify and Correct File Permissions with RPM
   # rpm -V docker 
   I would expect the results to look similar to this: 

S.5....T.  c /etc/sysconfig/docker-storage
S.5....T.  c /etc/sysconfig/docker-storage-setup

  - Here Size,digest,and mtime differ which is to be expected. 

.M.......    /var/lib/docker

  - Here the mode differs, this happens when you start docker for the first time docker changing the permissions on /var/lib/docker 

Fresh Install:
drwx------. 2 root root 6 May 17 01:17 /var/lib/docker/
-rw-------. 1 root root 218 Jul 21 11:55 /etc/sysconfig/docker-storage


After starting docker service: 
drwx--x--x. 10 root root 124 Jun 20 14:15 /var/lib/docker/
-rw-r--r--. 1 root root 218 Jul 21 11:55 /etc/sysconfig/docker-storage
