[ Upstream commit 8d1d4ff5e239d9ef385444bc0d855127d7b32754 ]
We set the default scnprint routines for the syscall args based on its type or on heuristics based on its names, now we'll use this for tracepoints as well, so move it out of syscall__set_arg_fmts() and into a routine that receive just an array of syscall_arg_fmt entries + the tracepoint format fields list.
