    strlcpy/strlcat: Remove references to snprintf
    
    While strlcpy and snprintf are somewhat similar, there's big differences
    between strlcat and snprintf which leads to confusion. Remove the
    comparison, since it's ultimately not that useful: the snprintf man page
    has similar language to strlcpy, so it doesn't provide a better
    reference. The two implementations are otherwise unrelated.
