- Rewrite SystemTimeOfDay QuerySystemInformation case. ReqSize is the amount of data copied to the user so use it accordingly. Also, fill up the buffer as much as the caller requested. Fixes 1 "ntdll_winetest.exe info".

- Use a newer (5.0 and higher) version of SYSTEM_TIMEOFDAY_INFORMATION structure (consisting of two additional 64 bits fields: boot time bias and sleep time bias).
