init.debug.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', so that BetterBug is able to write
these files.

Bug: 204381544

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/
