Subject: [PATCH] pdist-bootcheck: Run async update as transient service

Run the update as a separate service instead of as a forked
process to avoid the error message

    pdist-bootcheck.service: Failed to destroy cgroup /system.slice/pdist-bootcheck.service, ignoring: Device or resource busy

and to capture the exist status in systemd and the output in the
journal.
