    Simplify SortSupport for the macaddr data type
    
    As of commit 6aebedc38 Datums are 64-bit values. Since MAC addresses
    have only 6 bytes, the abbreviated key always contains the entire
    MAC address and is thus authoritative (for practical purposes -- the
    tuple sort machinery has no way of knowing that). Abbreviating this
    datatype is cheap, and aborting abbreviation prevents optimizations
    like radix sort, so remove cardinality estimation.
