trace: Simplify how st_print_trace_file_status() prints
st_print_trace_file_status() takes an fprintf()-like callback and a
FILE * to pass to it.
Its only caller hmp_trace_file() passes monitor_fprintf() and the
current monitor cast to FILE *. monitor_fprintf() casts it right
back, and is otherwise identical to monitor_printf(). The
type-punning is ugly.
Drop the callback, and call qemu_printf() instead.
