Find the fault package from log file.

Find the fault package from log file.

if it is available.

The data-provider-slave will leave the fault log if it finds a "SO" filename from the siganl handler.
And then if the master catches abnormal termination of slave provider, the master will try to open a
slave's fault log file. if it founds, the master will get the so filename from a log file.
and find the lbid using livebox-service API.

Previously, the master could not find the lbid correctly because of the old style code.
This patch will find the lbid from the DB.

*lbid = livebox Id (aka. dynamic box id)
