Unpack contents of downloaded archive into PyV8/%filename% folder inside Sublime Text Packages (find Browse Packages... menu item in ST2 editor to get into Packages folder), where %filename% is the name of downloaded file (e.g. it will be pyv8-win64-p3 if you download pyv8-win64-p3.zip file).
But the right dir path of sublimet 3 is /home/username/.config/sublime-text-3/Installed Packages, you should mkdir PyV8/pyv8-linux64-p3 in Installed Packages instead of Packages, then unpack the file that you download like pyv8-win64-p3.zip into it.
Manual installation says:
