src: ui: patch_hub: patch_hub_core: change message_box title

The subject of the "message_box" can be either sucess or error warnings,
but in some cases the title is simply the title of the current option in
process, what makes it not homogeneous and unclear.

To manage this situation, update the "list_patches()" message_box title
to "Error".
