perf tools: change machine__findnew_thread() to set thread pid

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

Note that callers sometimes want to find the main thread
which has the memory maps.  The main thread has tid == pid
so the usage in that case is:

	machine__findnew_thread(machine, pid, pid)

whereas the usage to find the specific thread is:

	machine__findnew_thread(machine, pid, tid)
