Merge #762: [Random] WIN32 Seed Cleanup: Move nLastPerfmon behind win…

…32 ifdef.

3f8c6b7 WIN32 Seed Cleanup: Move nLastPerfmon behind win32 ifdef. Code to avoid calling Perfmon too often is only needed when perfmon is actually going to get called. This is not intended to make any functional difference in the addition of entropy to the random pool. (21E14)
