If simple-touch ran on a compositor with multiple seats, and the first one happened to have the touch capability while the second one didn't, the handler for seat capabilities would destroy the wl_touch device it created on the first call for the first seat when it was called a again for the second seat that has not touch capabilities. Fix this problem by creating a separate struct for each seat. https://bugs.freedesktop.org/show_bug.cgi?id=78365
