timezone: use a symlink when updating /etc/localtime
Unless /etc/localtime is an existing file and not a symlink, then we will symlink instead of copying the tz_file to /etc/localtime. The copy was how older versions of Ubuntu handled this. Those versions should have a file /etc/localtime . When the symlink is preferred, then it should already exist in the image. LP: #1543025
