    kauth: fix clock skew detection
    
    Commit 5b3c1042969daec38ccb260e61d665eda0c713ea changed/removed some
    uses of abs() on unsigned time values. While the previous use of abs()
    was indeed incorrect, the result wasn't necessarily much better, even
    though it built with recent compilers, since it only checked for skew
    in one direction.
    
    Define and use a  macro to correctly evaluate the conditionals in 64-bit
    precision, avoiding C's integer promotion rules which prefer unsigned types
    (Date) to signed types of the same width (time_t on 32-bit systems).
