apache-poi: Introduce a separate jar-file for libs to reduce classes …

…included in coverage report

Introduce two jar-files to separate .class files into two jar files, one
which is included in coverage reporting and one which contains libraries
which should not appear in the coverage report.

Unfortunately this only allows control on "artifact" level, which means single
uninteresting classes/packages cannot be excluded.

Related to google#10826 and google#10860
