[SMT-LIB] :status unknown AUFLIA benchmarks

[Clark Barrett]

At the time these benchmarks were added to the library, no tool parsimg smt-lib
format could prove these unsat.  I plan to revisit these with updated tools in
the near future.

Is your tool available?  I like to get confirmation from more than one tool
whenever possible.
