Kernel-Related Fixes (#386) 

* Fix OrbisKernelBatchMapEntry struct

UE4 games and GTA V cause the BatchMap offset to overflow on Windows. Changing the type fixes this, and doesn't seem to cause any regressions on Windows or Linux.

* Implement posix_sem_trywait

Grand Theft Auto V needs this.

* Add missing scePthreadAttrGetdetachstate NID

Noticed this missing NID while testing games.
