common.cmake: downgrade C++ standard versionv4.0

I was testing the new version (C++20) with some existing code, and
immediately got build errors.

Apparently, now this:

    const auto s = u8"hello";

means that s has the type of const char8_t *const, where char8_t is some
batshit insanity with 0 backwards compatibility. For example, you cannot
make a std::string out of this??? Fuck that, and fuck C++ committee
morons.
