Touch the machine-id file

So is seems that if you remove the machine-id file it won't regenerate the file
but if you touch the file and leave it empty on boot it'll put a new machine-id
in the empty file. So work around this bug ("feature"?) by touching the file
so we don't have other issues in the process.
