DELIA-20610 : /opt overide of debug.ini does not work for tr69hostif

Reason for change: To allow the debug.ini overide from .opt folder.
Test Procedure: check the debug logs enabled from /opt/debug.ini file and tr69hostif process uses the same.
		1. Validate /opt overrides with this fix
		2. Validate the specific service logs in pace intel xg1v1 yoco build since it uses syslog-ng for logging
Risks: Low
