Change the user of update-manager.service to root

During the upgrade the service must run the delta.ua program supplied in
the delta.tar file to correctly execute the entire process.

Thus, it's infeasible to depend on POSIX file capabilities as the
delta.ua from upgrade package (delta.tar) will not have it.  This leaves
us with either (1) need to apply needed caps in runtime (de facto
requiring super privileges for the process controlling this action), or
(2) simplifying the process and changing the user of update-manager to
root.

This commit implements (2) option as, in practice, this program is
responsible for flashing complete platform images so it effectively has
every permission possible (as it can flash any data of its choosing)
