MFVSketch: Use datumIsEqual for comparing datums

mfvsketch used memcmp() for comparing two Datums to check for
equality. There is a note in the postgres/gpdb source saying
this is unsafe, so we converted it over to calling the postgres
function datumIsEqual() which can handle either little-endian
or big-endian byte order, making it more portable.
