[Instrumented libraries] Rebuild

The previous build was not a clean build, and was from before libc
was removed from the instrumented libraries.  Leaving libc in is not
an issue on the Focal bots, but will lead to runtime errors when
trying to run on other systems such as gLinux.  This CL clean builds
the instrumented libraries to remove libc.
