bottle-row: Set can-target and can-focus to false

The GtkListBox::row-activated signal only emits when
a row is activated, not the child widget. This means,
the check button wouldn't trigger the emission of
the signal, thereby not updating the
NewBottleDialog:selected-environment property.

Fixes #3740
