rsyslog: get alias of syslog back

since upstream rsyslog commit
https://github.com/rsyslog/rsyslog/pull/4317/commits/7a671da74f78047b3fd0eb65203f045de28cec0f
, Alias=syslog.service is removed from service file, which will make
systemctl restart syslog fail since Unit syslog.service not found when
we set rsyslog to default syslog.

And upstream have change the solution about pull 4317, so during next
upgrade, we need to add our own rsyslog.service, refer
