Subject: app-text/tesseract: Fix ScrollViewer

Use the system piccolo2d to build the ScrollViewer server. Stage it
manually instead of using install-jars so we don't have to sed through
the files and copy the bundled piccolo2d.

Many thanks to Olivier Diotte for the initial work on this. See
https://github.com/gentoo/gentoo/pull/719 for the details.
