[Instrumented libraries] No-op tarball rebuild

In the first CQ run on [1], there was a bug in //build/symlink.py that
truncated the source of symlink files to 0 size.  This caused ld-linux
on 2 bots to be broken.  Subsequent runs (I tried 9 run) all failed
even after the symlink.py bug was fixed because the broken file
remained on the bots.  This CL redundantly rebuilds the tarballs to
fix those bots so I can run the CQ to roll instrumented_libs.
