[PATCH] desktop-shell: destroy data before exiting.

From: "U. Artie Eoff" <ullysses.a.eoff at intel.com>
desktop-shell never returned from display_run() since it
was essentially killed when weston exited. To fix this,
it is necessary to watch for EPOLLHUP in window.c so that
toytoolkit clients will return from display_run() when
weston quits. This allows for clients to clean up
as needed.
