Fix for #2824798 (FW: crash when clicking "load" in the GUI):

- Fixed CineMetaEngine::listSaves(const char *target) which was broken.
- Also added explicit initialization of savegame descriptions to
  empty strings for safety reasons (e.g. arrays on stack aren't
  initialized to zero).
- Added explicit trailing zero setting to savegame descriptions
  (Previously using GMM you could write a description of length >= 20
  that had no trailing zero when written to description file (e.g. fw.dir)).
