Exclude org.apache.sis.util.resources package from javadoc.
Generate only aggregated javadoc, without per-module javadoc, for avoiding a build failure in sis-build-helper
and also for reducing disk usage consumption and possible confusion caused by all the duplicated HTML pages.
Note that we may need to define a profile for releases, since the later require per-module javadoc (we will
revisit this issue during the next Apache SIS release).
