* tests/sanity/namedprop.test: fix typo for proper output

* tests/core/ltl2dstar.test: Reduce the amount of tests performed on
one formula that is problematic for ltl2dstar.

Our use of
  ltl2tgba=ltl2tgba
  autfilt=autfilt
  ...
all over the test cases comes from the time where those tools were not
in PATH and we actually had something like
  ltl2tgba=../../bin/ltl2tgba
  autfilt=../../bin/autfilt

But today that is useless, and we prefer to write ltl2tgba rather than
$ltl2tgba, so let's remove this old cruft.

To ease debugging and testing, ltlsynt can output the synthesized
strategy as an automaton, not just an aiger circuit.
Also, its exit code has been changed to something meaningful.
