tracing/osnoise: Add __printf attribute to osnoise_print()

Browse Source 
Building kernel/trace/trace_osnoise.o with W=1 triggers the following
compiler warning:

  kernel/trace/trace_osnoise.c:96:17: warning: function 'osnoise_print'
  might be a candidate for 'gnu_printf' format attribute
  [-Wsuggest-attribute=format]

osnoise_print() forwards its format string and va_list arguments to
trace_array_vprintk(), which is annotated with __printf(3, 0).

Add the __printf(1, 2) attribute to osnoise_print() to silence the W=1
warning and enable compile-time format string checking for its callers.
