emacs.pkgs.ada-mode: pin wisi 3.1.3 to fix build

Apparently ada-mode is intended to be build with a _specific_ version of
wisi which is not mentioned in the manual (as far as I am aware), but
described in passing in NEWS [1]. Thus the package-overrides in ada-mode.el
are to be interpreted as a strict version requirement.
