init.gs201.rc: change permission of SJTAG writable files

Browse source 
On userdebug & eng builds, change permission of SJTAG writable sysfs files that need to be written to 'system'. This became necessary after HSUM separated main user from the SYSTEM user

Bug: 374645181
Flag: EXEMPT bugfix
Test: Ensure that there is "Privileged Debugging" item in BetterBug settings.
