tgbatest: implement a large part of ltl2tgba.test in c++

So that running valgrind is a lot more efficient.  Running
ltl2tgba.test using to take more than 15min.  We are now down to
25sec.

* src/tgbatest/checkpsl.cc: New file.
* src/tgbatest/Makefile.am: Add it.
* src/tgbatest/ltl2tgba.test: Adjust.
