Bump yml

Done as follows:

    find -name build.yml | xargs dirname | while read d ; do
        t=$(linuxkit pkg show-tag $d)
        ./scripts/update-component-sha.sh --image ${t%:*} ${t#*:}
    done
    git commit -s test pkg tools blueprints examples projects/kubernetes projects/swarmd docs linuxkit.yml Makefile src

This explicitly excludes projects/* which I did not know whether to update.

Then:

    git reset --hard
    for i in init runc containerd ca-certificates sysctl dhcpcd getty rngd ; do
        o=$(git grep -h "\(image:\|-\) *linuxkit/$i:[0-9a-f]\{40\}" origin/master:linuxkit.yml | awk '// { print $2 }')
        n=$(linuxkit pkg show-tag pkg/$i)
        ./scripts/update-component-sha.sh "$o" "$n"
    done
    git commit --amend projects

This updates any projects which were using components with the same hash as the
top-level linuxkit.yml.
