Subject: x11, wayland: do not accidentally close FD 0

Both backends have code to close each FD of their wakeup_pipe array.
This array is default-initialized with 0, which means if the backends
exit before the wakeup pipe is created (e.g. when probing), they would
close FD 0.

Initialize the FDs with -1. Then we call close(-1) in these situations,
which is perfectly allowed and has no bad consequences.
