Exclude jacocoagent from boot jars package check

This replicates the previous behavior when the boot jars package check
was performed by a singleton. When the singleton was removed and the
check was performed by the platform-bootclasspath the logic to exclude
jacocoagent from the list was lost. This change replaces it.
