RFR(xxs): [windows] Build broken on VS2010 after "8046148: JEP 158: Unified JVM Logging"

[Thomas Stüfe]

Hi all,

please review this tiny change. It fixes the build on windows/Visual Studio
2010 after "8046148: JEP 158: Unified JVM Logging".

strtoull() is missing from Visual Studio versions < 2013, but _strtoui64()
can be used instead.
