e_comp_wl_input: add wl_list_init() for safety of constraint's listener

There are a chance of E crash when wl_listener is removed
without initializing by calling wl_signal_add() and wl_list_init()

pointer_constraint_create()
-> (not calling pointer_constraint_enable())
-> pointer_constraint_destroy()
