[Xymon] Typo bug in stackio.c in release 4.3.7

Typo in lib/stackio.c in release 4.3.7 in line ~341:

   if (*dirname == '/') strcpy(dirfn, dirname); else sprintf(dirfn,

"%s/%s", stackfd_base, dirname);

    if ((dirfd = opendir(dirfn)) == NULL) {
            errprintf("Cannot open directory %s\n", fn);
            return;
    }

Should be something like:

    if (*dirname == '/') strcpy(dirfn, dirname); else sprintf(dirfn,

"%s/%s", stackfd_base, dirname);

    if ((dirfd = opendir(dirfn)) == NULL) {
            errprintf("Cannot open directory %s\n", dirfn);
            return;
    }
