smt2, btor: Revert calling memory_map -rom-only
This approach had major issues with ROMs whose initialization was not
fully defined. If required, memory_map -rom-only -keepdc should be
called early in a formal flow instead. (This does require a careful
choice of optimization passes though. Sby's scripts will be updated
accordingly.)
