[GNC] piecharts/linecharts turned blank in reports after upgrade

[Dong Lin]

Thanks Geert,

Yes, we can no longer display charts if GNC runs from the build directory.

This looks like a chartjs build issue.  If I create this link, charts
start showing.

ln -s $(src_dir)/borrowed/chartjs $(build_dir)/share/gnucash/chartjs

Maybe we can fix the CMake file to create the above link or copy the files
to the build directory.
