CMake: Enforce C++98 standard (without extensions)

We could perhaps get more precise warnings from the C++ compiler, if it
knew the standards version to use. This adds definitions for
CMAKE_CXX_STANDARD, CMAKE_CXX_STANDARD_REQUIRED and CXX_EXTENSIONS.

Technically Doomseeker conforms to the C++03 standard, but CMake has no
option for that; nonetheless they're very similar.

Fixes: #3542
