[virt-tools-list] [libosinfo] Fix osinfo_list_add_union()

[Zeeshan Ali (Khattak)]

From: "Zeeshan Ali (Khattak)" <zeeshanak at gnome.org>

This function was adding the second list elements to new list first so
the order of elements in the new list was contrary to what user will
expect of this function (and all wrapper/using functions).
