comp-wayland: use safe foreach when destroying outputs
wl_list_for_each dereference's output to increment the
next iteration of the loop. However, output is free'd
inside the loop resulting in a dereference to free'd
memory.
Use wl_list_for_each_safe instead, which is designed to
handle this kind of pattern.
