The log entry in results is altered to remove 'target_logs'. This
causes wrong log location in output.
e.g.
AssertionError: 1 != 0 : Log: /path/to/image/1.0-r0/postinstall.log
But when user wants to check the log, the user will find the log is
not present. The actual log file is /path/to/image/1.0-r0/target_logs/postinstall.log.
So fix to use the correct log location.
