[OE-core] [PATCH] update-rcd.bbclass: fix host/target test

[Ross Burton]

"update-rc: Stop and remove service if updating package" (oe-core d91b08) had a
bug in it's implementation of a "host or target" test which always resulted in
"target", so the rootfs scripts were attempting to restart daemons on the host.
