srogue: prevent overflowing the score file name.
If SCOREFILE is not defined, roguehome() is called to find a directory
for the score file. It copies up to PATH_MAX-20 bytes from an
environment variable to a static buffer. Later these are strcpy()'d to
scorefile, which is of size LINLEN. Unfortunately LINLEN is 80 and
PATH_MAX is at least 256. On Linux, it happens to be 4096.
I haven't yet managed to crash or exploit it, but there are surely no
beneficial consequences, so roguehome() has been modified to check the
length, and the string it returns is also checked in main().
