Remove 'make update'.

In the CVS days this used be a wrapper around either CVS or CVSup and
used to support updating src, doc, and ports checkouts.  With the move
to subversion this only supported updating src and was itself a
wrapper around 'svn update'.  With Git, users are probably better off
using appropriate Git commands directly to update without needing an
explicit make target as a wrapper.
