FS#609 - procd: implement runlevel 1

[openwrt-bot]

stintel:

Sysupgrade currently kills processes with SIGKILL if they don't shut down within 3 seconds after the SIGTERM signal. Some processes (e.g. domoticz) can take longer than 3 seconds to properly shut down. As this can potentially corrupt the sqlite database, it should be avoided.

While talking about this on IRC, it was suggested we should implement an "init 1" equivalent in procd. Adding this ticket as a reminder.

https://git.openwrt.org/87b583635475c56ae5b8ec89233f6f292ba09765 implements this for the sysupgrade case. I will investigate if it makes sense to add it to the shutdown/reboot case:
