Advanced Rogue family: fix some potential buffer overflows. Some code for determining the score file location assumed that PATH_MAX would be less than 1024, which cannot be guaranteed. Advanced Rogue 5 and 7, and XRogue, have had the buffers for the file name enlarged. UltraRogue never called the functions, so the code has been deleted instead.
