    include/stdckdint.h: make the header compatible with C++

    by removing the cast to _Bool.  The _Bool type is not defined for C++,
    and the specification from the gcc info doc states that the return
    type of the  __builtin_{add,sub,mul}_overflow() is bool already.

    This is done instead of including stdbool.h to avoid namespace
    pollution, since defining bool from stdckdint.h simingly is not
    sanctioned by ISO/IEC 9899:2024.
