tracing: Fix synth event printk format for str fields
The printk format for synth event uses "%.*s" to print string fields,
but then only passes the pointer part as var arg.
Replace %.*s with %s as the C string is guaranteed to be null-terminated.
The output in print fmt should never have been updated as __get_str()
handles the string limit because it can access the length of the string in
the string meta data that is saved in the ring buffer.
