Fixes #1570: raise the NTSTATUS returned by NtWow64* syscalls

[erwan-le-pape]

The NtWow64* syscalls in process_info.c fail to save the returned NTSTATUS to pass in the raised exception, instead relying on GetLastError which is not set and returns 0.

This PR saves the returned status and uses psutil_SetFromNTStatusErr to raise the appropriate error instead of PyErr_SetFromOSErrnoWithSyscall.

Good catch. Could you please limit lines to 80 chars (e.g. like this:

            psutil_SetFromNTStatusErr(
                status,
                "NtWow64QueryInformationProcess64(ProcessBasicInformation)");

...) and also update CREDITS file?.
