dmidecode: Add helper functions pr_list_start/item/end

Print lists through helper functions. pr_list_start() starts the
list, with an optional value. pr_list_item() prints a single item.
pr_list_end() is a no-op for plain text output, but is in place in
anticipation of supporting other output formats such as HTML.
