js: update select2 to 3.5.4

(4.x seems like a more major upgrade - we stick to the 3 series for now.)

Note that select2-bootstrap.css *not* is upgraded. It is a separate thing (see
LICENSE.md) and currently unused. (Select2 now has similar functionality built
in - that should perhaps be used with Bootstrap instead.)
