    traceroute: Silence compiler warning
    
    Silence the warning:
    
    argument to 'sizeof' in 'strncpy' call is the same expression as the
    source; did you mean to use the size of the destination?"
    
    by using strlcpy() and the size of the destination (device).
    
    No functional change intended.
