don't overwrite chrome.manifest

this hopefully makes the monkey patch update persistent.

Note: instead of using FileUtils, this would be another method:
  const {Services} = Cu.import('resource://gre/modules/Services.jsm');
  let manifest = Services.dirsvc.get('GreD', Ci.nsIFile);
  manifest.append('legacy.manifest');
