VirtualQueryEx, called by fixup_mmaps_after_fork, requires PROCESS_QUERY_INFORMATION permissions per MSDN. However, testing shows that PROCESS_QUERY_LIMITED_INFORMATION is sufficient when running the same code on Windows 8.1 or Windows 10. Fix the code to give the forked child always PROCESS_QUERY_INFORMATION perms on Windows Vista/7 and respective server releases. Revert now unneeded patch to check_token_membership as well.
