[benchmarks] Add fuchsia.boot.RootJob to component manifests.

The corresponding shell scripts for these component manifests all use
the 'killall' shell command. This command uses the root job, gained from
/dev/misc/sysinfo. Soon I'll change the 'killall' command to use
fuchsia.boot.RootJob and to prevent CI from rejecting the change, I need
to add the service to these component manifests ahead of time.

Bug: 25045
