Map: add missing sresize in new_game_desc(). Every time we append to the string 'ret', we check first that there's enough space, and realloc it larger if it's getting close to full. Except that I missed one case at the join between the two parts of the encoding. (Spotted because apparently on someone's build platform this led to a compiler warning that 'ret' might be null. I think _that's_ not a serious worry, but the missing resize was definitely unintentional.)
