update-motd: use a marker file to hide esm updates information

Instead of a flag passed to the script, check for the existence of a marker file coming from the Pro Client. This implements the same control level for both tools.

[Renan Rodrigo (renanrodrigo)]

This one a merge proposal against the git-ubuntu branch, as there is no `xenial` branch in the actual git repo.
