common: Allow init shell script to set USB configfs related properties

init.qcom.usb.sh needs to set sys.usb.controller and sys.usb.configfs
properties for using configfs approach. Hence add required permission
for same to overcome below seen denials.

init: avc: denied { set } for property=sys.usb.configfs pid=3345
uid=0 gid=0 scontext=u:r:qti_init_shell:s0
tcontext=u:object_r:system_radio_prop:s0 tclass=property_service permissive=0

init: avc: denied { set } for property=sys.usb.controller pid=3345
uid=0 gid=0 scontext=u:r:qti_init_shell:s0
tcontext=u:object_r:system_radio_prop:s0 tclass=property_service permissive=0
