Implement memory unmapping for Sony PS/3

(part of commit 9379c66 from Unity-Technologies/bdwgc)

Issue #173 (bdwgc).

* os_dep.c [USE_MUNMAP && !MSWIN32 && !MSWINCE && SN_TARGET_PS3]:
Include sys/mman.h instead of sys/memory.h.
* os_dep.c [USE_MUNMAP && !USE_WINALLOC && SN_TARGET_PS3]
(GC_unmap): Call ps3_free_mem() instead of mmap().
