Minor Kernel Fixes (#1529)

Browse source 
* Skip destruction of adaptive mutex initializers

Based around similar behaviors implemented in the more-kernel branch. Hatsune Miku Project Diva X needs this.

* Fix posix_lseek result overflow

Seen when testing Spider-Man Miles Morales on more-kernel.

* Add posix_fsync

Used by Spider-Man Miles Morales. I've added the normal posix error handling to this function, though I'm aware sceKernelFsync doesn't return any errors currently. This is for future proofing and accuracy, as the actual libkernel does the usual error handling too.

* Properly handle VirtualQuery calls on PoolReserved memory.

* Export posix_getpagesize under libkernel

Bloons TD 5 needs this.

* Clang
