Subject: [PATCH] wayland: send key-down events for modifier keys

Presently, Muffin sends key-up events for modifier keys but no key-down
event. This breaks applications that use a modifier key standalone, such
as the Shift-click functionality in browsers, games which use modifier
keys seperately, and Wine, where modifiers are rendered completely
non-functional due to how its input model works. This commit fixes
those issues.

Closes: linuxmint/wayland#1
