mach: Use PAGE_SIZE
The PAGE_SIZE from the Mach headers statically defines the machine's
page size. There's no need to query it dynamically; furthermore, the
implementation of the vm_statistics () RPC unconditionally fills in
pagesize = PAGE_SIZE;
Not doing the extra RPC shaves off 2 RPCs from the start-up of every
process!
