Selfrando does not play well with delay loading on Windows

[ahomescu]

The MSVC linker on Windows supports delay loading, where a DLL is only loaded when one of its exports is called for the first time, as opposed to program startup, somewhat similarly to lazy linking on Linux. On Windows, this implementation relies on a helper function called __delayLoadHelper2 which is available in the delayimp library. However, randomization moves this helper function around, which breaks delay loading.

For now, we just disable delay loading. However, delay loading can significantly reduce startup times, so we should find a way to support it.
