xmb_free_node() frees the console name each horizontal-list node
owns, so the playlist and Explore view tabs no longer leak it when
the list is torn down (the 4-byte leaks in #20065).
menu_icon_ownership now ends through main_exit(), so the menu
driver's free() runs, and its xmb lane counts the copies of the
fixture playlist's name made with strdup (link-wrapped) that are
still unfreed afterwards.
