    list-base: Set view longpress to GTK_PHASE_CAPTURE
    
    There's an issue with how GtkGestureLongPress functions where if the
    gesture is in phase BUBBLE and another gesture in CAPTURE claims
    the sequence, the prior LongPress will emit a ::pressed event
    regardless.  More specifically, our code doesn't work because the
    drag gesture in GtkListBase (which tracks if rubberband should be
    stopped) prevent events from being sent to our view long press gesture.
    This makes the background menu pop-up unexpectedly while dragging
    on a touchscreen.
