Re-zip the omni.ja files

Re-zipping the omni.ja files is not needed to make them reproductible,
however if we don't re-zip them, the files become corrupt when we
update them using 'zip' (we are doing that when we update the
000-tor-browser.js preference file to set the locale) and firefox will
silently fail to load some parts.
