Repair Exec['update_apt'] to run apt-get update when needed.

Move this Exec to a dedicated class that is not included by default i.e. we
default not to "apt-get update" on every Puppet run.

We now make use of this class in the apt::upgrade_package define to make sure
APT indexes are up-to-date before attempting package upgrades.

One may now use the following to ensure current packages are installed by
Package resources:

  include apt::update
  Package { require => Exec[apt_updated] }
