usb: modify the permission of USB gadget hal

Browse source 
Currently, USB gadgdet hal couldn't access configfs nodes during
device booting. The permission of configfs nodes are root as default,
and they are modified to system by init process. Therefore, USB
gadget HAL can't access them before permission changes completely.

The patch will modify permission of USB gadget hal so that it can
access configfs nodes without permission change.

Bug: 204378488
Test: check connection time
