tracing: Make tp_printk work on syscall tracepoints
Currently the tp_printk option has no effect on syscall tracepoint.
When adding the kernel option parameter tp_printk, then:
echo 1 > /sys/kernel/debug/tracing/events/syscalls/enable
When running any application, no trace information is printed on the
terminal.
Now added printk for syscall tracepoints.
