fix: build resources into subplot binary even in Debian package

Once upon a time, in a galaxy far, far away, we decided to not build
the share/* resource files into the subplot binary, when building it
for a Debian package. Much later, we were much surprised when this was
not the case and tests fail when run during the Debian package build.

Because it's surprising to not build in the resources for a Debian
package, we hereby undo that decision.
