gitk: Replace "next" and "prev" buttons with down and up arrows

Users often find that "next" and "prev" do the opposite of what they
expect.  For example, "next" moves to the next match down the list, but
that is almost always backwards in time.  Replacing the text with arrows
makes it clear where the buttons will take the user.
