Kick hotkeys on release, not press
I use keymap_options=grp:lctrl_lshift_toggle for layout switching.
But Weston handle key bindings on press and not release, so I can't use ctrl-shift-tab in Firefox
or ctrl-shift-c for copy terminal output.
The Xorg has the same bug, described here: https://bugzilla.freedesktop.org/show_bug.cgi?id=865
