CMake: Remove duplicated check for sigc++

- It didn't make much sense to check twice anyway
- The additional check for C++11 is not required anymore after r15039 as we use -std=c++11 by default now
- The check broke subsequent cmake runs on Windows (i.e. compilation broke whenever a .cmake file changed and CMakeCache hat to be cleared manually)
