FATAL ERROR: DB file open failed - patch

[mohan43u]

When I tried run_root_shell, I got this message "FATAL ERROR: DB file open failed" even if both device.db and run_root_shell are in same directory. When I changed DEVICE_DATABASE_FILE to full path like "/data/local/tmp/device.db", then It started working.

So I did some changes to device_database.c (I dont know how to attach a patch in github issue, so I'm pasting my diff here. Please make this change on your branch)
