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.
