menuconfig: Avoid needlessly turning on show-all in rare cases

Loading a new configuration with the cursor on an invisible item with
visible children (can happen with optional prompts) would needlessly
turn on show-all, even though such invisible items are always shown.

Fix it by doing a more explicit check for whether the selected item
shows up in the menu after loading the configuration, like
_toggle_show_all() and _jump_to() do.
