The problem is triggered by configuring a bad path to Xwayland in
weston.ini, which causes exec() to fail. The fork() succeeded though,
which means the weston_process was already on the watch list, and the
watch can be handled, making sigchl_handler() leave the link
uninitialized.
Making sure the link remains removable fixes this.
