[meta-arago][dunfell][PATCH] weston-init: fix killproc for thinlinux so that it doesn't kill itself

[Darren Etheridge]

busybox pidof doesn't omit the current pid
as this script is called weston on the target
in thinlinux with a busybox based utility load
later killproc operations end up killing this
script, which leads to the script not actually
starting weston.
