Subject: [PATCH] fix wow64 registry mode on windows 2000

CMake fails to find any registry paths on Windows 2000 and according to regmon
it fails with an access denied error. I double checked all the access rights
and they are fine. After checking the access modes on MSDN I found that it says
KEY_WOW64_32KEY / KEY_WOW64_64KEY are not supported on Windows 2000. CMake does
not check if the current system supports Wow64 before applying these flags.

This patch adds a check for IsWow64Process in kernel32.dll before adding these
flags. Maybe this should be in a helper function, but I don't really know the
codebase well enough.
