sceNetAdhocMatching: Start returns 0, not the matching thread's ID

Browse Source 
The fake matching thread was started through sceKernelStartThread,
which switched threads inside the call, and the game got the new
thread's ID back. On a PSP, Start returns 0 (pspautotests
net/adhoc/matching). Create and start it like adhocctl's thread instead.
