            Log:
            enable the logging_syslogd_append_public_content boolean

The test reproduces scenarios described in 2 different bugs. One of
them is BZ#1823672. If this scenario should succeed, a newly introduced
boolean called logging_syslogd_append_public_content needs to be enabled.
The scenario also requires that the target log file exists before
the rsyslogd process tries to append to it.
