For debugging watchdog issues in system_server, system_server needs read access to binder-state file. Access to generic debugfs has been removed for all processes except init, vendor_init & dumpstate. This CL labels /sys/kernel/debug/binder/state file and allows system_server, dumpstate, vendor_init & init, 'r_file_perms' access to the same file. The label and the associated access permissions only apply to userdebug builds. Change-Id: I159e39bcd05d699454797f8b1d1c17c810c99cb1
