Rewrite the ltl2tgba bench using ltlcross

* bench/ltl2tgba/sum.py: New file.
* bench/ltl2tgba/.gitignore, bench/ltl2tgba/Makefile.am,
bench/ltl2tgba/README, bench/ltl2tgba/algorithms, bench/ltl2tgba/big,
bench/ltl2tgba/defs.in, bench/ltl2tgba/known, bench/ltl2tgba/small:
Rewrite this benchmark completely.  Also drop support of Wring and
Modella, as we cannot get them to work reliably.
* bench/ltl2tgba/formulae.ltl: Rewrite in Spot's syntax.
* bench/ltl2tgba/lbtt2csv.pl, bench/ltl2tgba/ltl2baw.in,
bench/ltl2tgba/parseout.pl: Delete these scripts, no
longer needed.
* configure.ac: Do not output ltl2baw.pl anymore.
