shutdownd: kill the old implementation

Not that all functionality has been ported over to logind, the old
implementation can be removed. There goes one of the oldest parts of
the systemd code base.

-/* The scheme is very simple:
- *
- * To schedule a shutdown, simply fill in and send a single
- * AF_UNIX/SOCK_DGRAM datagram with the structure above suffixed with
- * the wall message to the socket /run/systemd/shutdownd (leave an
- * empty wall message for the default shutdown message). To calculate
- * the size of the message, use "offsetof(struct sd_shutdown_command,
- * wall_message) + strlen(command.wall_message)".
- *
- * To cancel a shutdown, do the same, but send a fully zeroed-out
- * structure.
- *
- * To be notified about scheduled shutdowns, create an inotify watch
- * on /run/shutdown/. Whenever a file called "scheduled" appears, a
- * shutdown is scheduled. If it is removed, it is canceled. If it is
- * replaced, the scheduled shutdown has been changed. The file contains
- * a simple, environment-like block that contains information about
- * the scheduled shutdown:
- *
- * USEC=
- * encodes the time for the shutdown in usecs since the epoch UTC,
- * formatted as a numeric string.
- *
- * WARN_WALL=
- * is 1 if a wall message shall be sent
- *
- * DRY_RUN=
- * is 1 if a dry-run shutdown is scheduled
- *
- * MODE=
- * is the shutdown mode, one of "poweroff", "reboot", "halt", "kexec"
- *
- * WALL_MESSAGE=
- * is the wall message to use, with all special characters escaped in C-style.
- *
- * Note that some fields might be missing if they do not apply.
- *
- * Note that the file is first written to a temporary file and then
- * renamed, in order to provide atomic properties for readers: if the
- * file exists under the name "scheduled", it is guaranteed to be fully
- * written. A reader should ignore all files in that directory by any
- * other name.
- *
- * Scheduled shutdowns are only accepted from privileged processes,
- * but anyone may watch the directory and the file in it.
