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.
