vagrant: Rearrange steps of provision script

- Disable automatic upgrades earlier in the script. This makes it more
  likely that unattended-upgrades will be disabled before it has a
  chance to run.

- Move apt commands to the end. In the event that unattended-upgrades
  is running anyway, these command can fail and cause further steps to
  be skipped.

Closes #1506
