Use LPCVOID instead of 'const LPVOID' for VerQueryValue.

Apparently "const LPVOID" is different from "LPCVOID".  You can see
the difference for yourself by trying to compile this small bit of C
code:

  #include <windows.h>
  void x(const LPVOID);
  void y(LPCVOID);
  void test() {
    const char * data;
    x(data);
    y(data);
  }
