Remove fs-extra

For the most part this was just a matter of using fs.promises. One
utility function was necessary for unlinking a file without erroring if
it doesn't exist since that functionality doesn't exist in Node.

I removed the Mac directory copy instead of refactoring it since we've
had this for a long time now and I think it's safe to assume that users
running code-server on Mac don't have the old directory anymore.
