Fix sceKernelSelfStopUnloadModule parameters

According to http://code.google.com/p/jpcsp/source/detail?r=3597
Tom Clancy's Splinter Cell Essentials and Ghost in the Shell Stand Alone Complex are still booting
I think sceKernelStopUnloadSelfModuleWithStatus may be wrong.  It doesn't match the SHA.  But I'm not sure what the right name is, might just be truncated.

sceKernelSelfStopUnloadModule is definitely right.
