On userdebug & eng builds, change the owner/group of SJTAG sysfs files that need to be written to 'system'. This became necessary after these files were migrated out of DebugFS, as write access to the world is no longer supported. Bug: 188817349 Test: Ensure that the writable files in the following directories have 'system' as their owner & group: /sys/devices/platform/sjtag_ap/interface/ /sys/devices/platform/sjtag_gsa/interface/ Signed-off-by: Peter Csaszar <pcsaszar@google.com> Change-Id: I4420fccd92522a48f44b80bd0a19f4a20eb32442
