ltlgrind: improve error message when formulas are missing

Browse source 
The error message, inherited from ltl2tgba, used to say "No formula to
translate", but "translate" isn't appropriate here.

* bin/common_finput.cc, bin/common_finput.hh (check_no_formula): Allow
"translate" to be changed.
* bin/ltlgrind.cc: Change it.
* tests/core/ltlgrind.test: Test it.
