* lib/tempfile.rb: fix confusing inspect.

  previous Tempfile#inspect says it is a File, but actually
  it is not a File.

    t = Tempfile.new("foo") #=> #<File:/tmp/foo20121106-31970-1ffbum0>
    t.is_a? File #=> false

  now Tempfile#inspect returns like:

    t = Tempfile.new("foo")
    #=> #<Tempfile:/tmp/foo20121106-31970-1ffbum0>
