checkAUTHORS.pl - delete and replace with updateAUTHORS.pl

updateAUTHORS.pl now can replace all the capabilities of
checkAUTHORS.pl, and checkAUTHORS.pl has a slightly different idea of
what needs to be validated, and is not aware of the
Porting/exclude_contrib.txt. Instead of teaching it to be aware and
maintaining two tools this drops checkAUTHORS.pl

In the process we move the logic for t/porting/pending-author.t into
t/porting/authors.t, by letting updateAUTHORS.pl do it as well. This is
helpful because updateAUTHORS.pl contains similar core git logic so that
it can implement some of its options.
