Florian Müllner 566d566f26 alt-tab: Do not hardcode ALT modifier
While we allow for arbitrary modifiers in keybindings, both the
alt-tab and ctrl-alt-tab popups close when ALT is not present in
the modifier mask, resulting in ALT being de-facto hardcoded.
Instead, pass the actual modifier mask when invoking the popups.
