Fix QLabel crash if buddy's lifetime is too short
If buddy is deleted then QLabel will still try to deliver the
shortcut event to it, in QLabel::event(), and cras.
Besides connecting to destroyed() which alone fixes the crash,
also hardened it and guarded against dereferencing null buddy,
in the unlikely event of someone adding features to QLabel.
The second part is suitable for backporting to the LTS branches.
