            Log:
            test if icecast can rotate its log files

When the icecast service is running for a long time, its log files
become large enough so that they will be rotated. Unfortunately,
SELinux prevents the rename of old log files. The TC reproduces
the situation.

In order to support the functionality of `logsize` and `logarchive`
options, I believe that SELinux policy should allow the actions.
The TC looks for appropriate policy rules and file context patterns.

The TC covers BZ#2156763.
