shm_open is a POSIX function creating an in-memory file. Using it simplifies
the code and removes the dependency on XDG_RUNTIME_DIR. The only downside is
that we need to generate a random name for the shm file.
To prevent wl_keyboard keymap being written to by clients, use a unique
file descriptor for each wl_keyboard resource.

After destroying a keyboard input device, seat's listeners could still be pointing to destroyed wlr_input_device signals. This patch makes sure the references are removed while the input device is being destroyed.
