use bdd_restrict more

Browse source 
Doing so reduced the number of GC passes tested in bdd.test, which is
good.

* spot/twaalgos/ltl2tgba_fm.cc: Simplify minato loops with
bdd_restrict.
* spot/twaalgos/synthesis.cc (split_2step): Use bdd_restrict instead
of bdd_appex.
* tests/core/bdd.test, tests/core/ltlf.test: Adjust test cases.
