Add a new parameter for 'pid' to machine__findnew_thread().
Change callers to pass 'pid' when it is known.

event->ip.tid? at a minimum current functionality is retained with
machine__findnew_thread(machine, 0, event->ip.pid)
perf tools records mmap information against the process's main thread
for which pid == tid. So the correct values are being passed here.
