sfeed_xmlenc: be more paranoid in printing encoding names
sfeed_xmlenc is used automatically in sfeed_update for detecting the encoding. In particular do not allow slashes anymore either. For example "//IGNORE" and "//TRANSLIT" which are normally allowed. Some iconv implementation might allow other funky names or even pathnames too, so disallow that. See also the notes about the "frommap" for the "-f" option. https://pubs.opengroup.org/onlinepubs/9699919799/utilities/iconv.html + some minor parsing handling improvements.
