tgbatest: drop support of Spot's legacy format from ltl2tgba

This is progress for #1.

* src/tgbatest/ltl2tgba.cc: Remove options -b and -X.  Change
-P to read HOA files instead.
* src/tgbatest/complementation.cc: Replace option -b by -H for
HOA output, and read files in HOA.
* src/tgbatest/complementation.test, src/tgbatest/cycles.test,
src/tgbatest/dbacomp.test, src/tgbatest/degenid.test,
src/tgbatest/dfs.test, src/tgbatest/emptchke.test,
src/tgbatest/ltl2tgba.test, src/tgbatest/renault.test,
src/tgbatest/satmin2.test, src/tgbatest/sccsimpl.test,
src/tgbatest/sim2.test: Adjust.
