sepolicy: Update policy for secure components

Playready stores license under /data/data/app_ms. All TZ apps including
Playready would create their own directory under /data/misc/qsee.
To get test apps working with older dir structure, userdebug mode
build would have permision to create directory under /data/data.
Test apps based on newer targets must move to new structure.
Also add policies for secureUI.
