improve coverage of LaTeX/utf8 printers for SERE

* bin/common_output.cc, bin/common_output.hh,
bin/randltl.cc: Adjust so that running "randltl -S" use
the SERE flavor of the spot/latex/utf8 formula printers.
* tests/core/latex.test, tests/core/utf8.test,
tests/python/ltlparse.py: Add more test cases.
