init.gs101.rc: Change owner/group of SJTAG files

Browse source 
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/
