[PATCH weston] shell: fix segfault in fullscreen binding

[Boyan Ding]

Commit 9aa8ce69 'shell: Don't use the helper methods in xdg_shell
implementations' forgot to set shsurf->fullscreen_optput in
fullscreen_binding(), causing weston to segfault when fullscreen
with the mod + shift + f binding. This patch fixed that issue.
