52053: whitelist capability CAP_WAKE_ALARM
Since the systemd update v254 from July 28, 2023, the capability 'CAP_WAKE_ALARM' is passed by default to some user process (especially desktop managers). Since 'CAP_WAKE_ALARM' is very narrow in focus, it is preferable that zsh does not consider it as a 'privileged' capability.
