tracing: append a comma to INIT_FTRACE_GRAPH
Impact: dont break future extensions of INIT_TASK
While not a problem right now, due to lack of a comma, build fails if
elements are appended to INIT_TASK() macro in development code:
arch/x86/kernel/init_task.c:33: error: request for member `XXXXXXXXXX' in something not a structure or union
arch/x86/kernel/init_task.c:33: error: initializer element is not constant
arch/x86/kernel/init_task.c:33: error: (near initialization for `init_task.ret_stack')
make[1]: *** [arch/x86/kernel/init_task.o] Error 1
make: *** [arch/x86/kernel] Error 2
