Fix install rules for generated _en.ts files
Fix install rules for generated _en.ts files

Commit aabb833032fa44c7 introduced _en.ts files that are auto-generated
in the build directory. However, $$files() in this case returns
absolute paths, which the text substition rules later on adds again.

Fix this by first removing the absolute path.
