rustbuild: Tweak where timing information goes

This commit tweaks where timing and step information is printed out as part of
the build, ensuring that we do it as close to the location where work happens as
possible. In rustbuild various functions may perform long blocking work as
dependencies are assembled, so if we print out timing information early on we
may accidentally time more than just the step we were intending to time!
