IMPALA-7560: Set selectivity of Not-equal

Calculate binary predicate selectivity if one of the children is
a slotref and the other children are all constant.
eg. something like "col != 5", but not "2 * col != 10"

selectivity = 1 - 1/ndv

Testing:
Modify the function testNeSelectivity() of the
ExprCardinalityTest.java, change -1 to the correct value.
