DVE2: Do not display state variables with only one possible value.

Browse source 
* iface/dve2/dve2.cc (dve2_kripke::dve2_kripke): Fill
a format_filter_ array with boolean indicating whether each
variable should be printed.  Ignore variable with only one
possible value.
(dve2_kripke::~dve2_kripke): Destroy it.
(dve2_kripke::format_state): Use it.
* iface/dve2/finite.test: Adjust.
