Speedup reduc.test by not spawning one process per formula. 

* src/ltltest/reduc.cc: Add an option -f to read a lost of
formulae from a file.  Running a process for each formula was
too slow.  Also add an option -h to hide reduced formulae.
* src/ltltest/reduc.test: Simplify accordingly.

Move the last test from emptchk.test to emptchke.test.
