Fix sys_ppu_thread_start error checking, fix rare bug in sys_ppu_thread_create

Browse source 
* Correct error code to EBUSY.
* lv2_obj::awake was called even when EBSUY should be returned.
* Fix sys_ppu_thread_create for a newly created thread with the same id as ppu_thread::id_base. (can happen if main thread exited before its creation)
