    osdep/linux/ofpath: Update strstr() calls

    With C23, strstr() returns a "const char *" if its first argument is
    "const char *", and these changes are implemented in glibc-2.43.

    As a result, the first strstr() call in check_sas() now returns a "const
    char *" instead of "char *" because sysfs_path is a "const char *". This
    triggers a "discards qualifiers" warning, that is later promoted to an
    error and ultimately causes the build to fail.

    To fix the issue, this patch converts "ed", the pointer that stores
    strstr()'s return value, to a "const char *". Removes the xstrdup()
    call and cleans up the rest of the function by updating the *printf()
    calls and using pointer arithmetic to compute lengths instead of strlen().
