Alexey Kardashevskiy 819b58b09f ppc64: Increase page size ...

The default configuration on PPC64 uses 64K system page size. Having it
4K was not a problem until recently when 365fba2440cee3aed74c77
"executor: surround the data mapping with PROT_NONE pages" added
surrounding mappings not aligned to the actual system page size.

This changes the page size for ppc64 to 64K and introduces the upper
limit to randPageCount() as we have the hard coded limit of 16MB.
If the unlikely event of a PPC64 system with 4K pages, we will end up
allocating less pages which is not great but acceptable.

This avoids using os.Getpagesize() as the page size on a building host
may be different than on the test machine so we always use the bigger
size for simplicity.
