Bugfixes - minidump load, memory tail boundary (#568)

Minor change to allow minidump load to work with pages with copy
permission set.

File was probing memory via VirtualQuery incrementally, previously this
ran forever as Sogen doesn't replicate Windows behaviour.

Added exclusive allocation end boundary so that allocation / info check
on last page of user space VA works. Modified
memory_manager::find_free_allocation_base and
memory_manager::get_region_info to use exclusive boundary.
Added check to NtQueryVirtualMemory - now correctly returns
STATUS_INVALID_PARAMETER when run against memory outside of user space
VA. Kernel modules should use ZwQueryVirtualMemory not the user land
API.
