Add org.osgi.service event and cm jars to javadoc-build classpath

[HannesWell]

This is intended to fix the java-doc build that currently fails (mentioned in eclipse-equinox/equinox#18 (comment)):
https://download.eclipse.org/eclipse/downloads/drops4/I20220618-1800/compilelogs/platform.doc.isv.javadoc.txt

Based on #19 just the jars of the missing packages are added.

Is there a quick way to test if this works or will we just see with the next I-build?

Unfortunately the fix is not complete https://download.eclipse.org/eclipse/downloads/drops4/I20220619-1800/compilelogs/platform.doc.isv.javadoc.txt :

Note that this direct-from-maven package just showed up in the I-Build repository a few minutes ago and was not there 2 hours ago, so maybe this problem fixed itself now...

This happened when @sravanlakkimsetti marked https://download.eclipse.org/eclipse/downloads/drops4/I20220619-1800/ as stable . I'll run new I-build to confirm.
