Bug 36948: Resolve SIP issues in D12

My Koha testing docker SIP started dying repeatedly after launch. After investigation, I
found it was a problem with logging and default ports.

In D12 there is no syslog anymore, everythign uses journal. Four our purposes, lets log SIP issues
to sip.log by default

Attaching a patch to clear things up.

To test:
1 - Open KTD/D12
2 - tail -f /var/log/koha/kohadev/*.log
3 - On another terminal 'restart_all'
4 - Wait a bit, notice SIP dying
5 - Apply patch
6 - Update SIPconfig:
    server-params:
    log_file='/var/log/koha/kohadev/sip.log'
    service with port 8023:
    port="127.0.0.1:8023/tcp"
7 - Restart all
8 - Confirm SIP no longer dies
