Tested this by setting up a local Vagrant instance using the following
procedure:
1. Made a fresh minion/master install (using salt-bootstrap) of version
2014.1.10.
2. Adding a `test.ping` ACL rule for the `vagrant` user.
3. Asserting that I couldn't execute `salt '*' test.ping'` as `vagrant`
user.
4. Applying `chmod 755 /var/cache/salt /var/cache/salt/master/jobs
/var/run/salt /var/run/salt/master`.
5. Verifying that `salt '*' test.ping'` now works.
Fixes#16318.
