Switch to relative imports in .ts files

With the upcoming rules_js switch, I could only get relative imports
to work reliably. The absolute imports didn't work in some
circumstances. This patch gets all non-scouting directories moved to
relative imports. The motivation here is to keep the final switchover
patch as small as possible.
