[Darwin] Use vm_kernel_page_size for WTF::pageSize().
<https://webkit.org/b/154726>
Reviewed by Antti Koivisto.
Source/WebKit2:
Use WTF::pageSize() for the SharedMemory page size.
* Platform/mac/SharedMemoryMac.cpp:
(WebKit::SharedMemory::systemPageSize):
Source/WTF:
Make sure we use the right VM page size on Darwin systems.
On devices where the native page size is 4 KB, it's both
possible and profitable to madvise in smaller chunks.
* wtf/PageBlock.cpp:
(WTF::systemPageSize):
