[OE-core] [PATCH 3/4] sysklogd: Use update-alternatives

[Khem Raj]

busybox also provides klogd and syslogd, this change makes it coexist
peacefully. Currently rootfs fails in situations where both of them are
providing these binaries and busybox postinsts fail

update-alternatives: Error: not linking
/mnt/a/oe/build/tmp/work/qemuriscv64-bec-linux/core-image-full-cmdline/1.0-r0/rootfs/sbin/klogd
to /bin/busybox.nosuid since
/mnt/a/oe/build/tmp/work/qemuriscv64-bec-linux/core-image-full-cmdline/1.0-r0/rootfs/sbin/klogd
exists and is not a link
