libcereal: Disable c++11-narrowing-const-reference warning as error

Clang 18 is fussy about it

Fixes

unittests/map.hpp:65:25: error: non-constant-expression cannot be narrowed from type 'typename std::enable_if<std::is_integral<char>::value && sizeof(char) == sizeof(char), char>::type' (aka 'char') to 'const signed char' in initializer list [-Wc++11-narrowing-const-reference]
