ath79: sysupgrade: remove obsolete sysupgrade watchdog kill

The watchdog kill command was meant for busybox watchdog. Busybox watchdog
was replaced by the procd watchdog mid 2013 with commit df7ce9301a25
("busybox: disable the watchdog utility by default"), which makes the kill
command obsolete since quite some time.
