Original change's description:
> [copy][ninja] Move copy_sky_engine_sources.py to Python3
>
> Python2 doesn't support nanosecond timestamps, but ninja does for
> checking dirtiness of builds. Because python2 is being used to copy the
> sources from the dart dir to the output dir in Fuchsia builds, doing a
> second build immediately after the first one results in the build still
> being dirty and the steps repeated.
>
> In order to fix this, simply update this script to Python 3.x which
> handles nanoseconds in mtimes.
>
> Bug: 36581
