I.e., SERE without star, or LTL formula using only X and Boolean
operators.

* src/ltlast/formula.hh, src/ltlast/formula.cc: Add a bit for
tracking finite formulas.
* src/ltlast/atomic_prop.cc, src/ltlast/automatop.cc,
src/ltlast/bunop.cc, src/ltlast/constant.cc, src/ltlast/formula.cc:
Adjust.
* src/ltlast/unop.cc, src/ltlast/binop.cc: Adjust and use that
bit to refine the computation of some LTL classes.
* src/ltltest/kind.test: New tests.
