utils: Introduce nftnl_parse_str_attr()HEADmaster
Wrap the common parsing of string attributes in a function. Apart from slightly reducing code size, this unifies callers in conditional freeing of the field in case it was set before (missing in twelve spots) and error checking for failing strdup()-calls (missing in four spots).
