infinoted: Use privileged decorator for actions

Tests:

- Functional tests work
- Initial setup succeeds
  - infinoted user/group is added to the system
  - systemd service is created and service is running after install
  - Directories /var/lib/infinoted, /etc/infinoted and /var/lib/infinoted/sync
    are created with infinoted as owner and group.
  - Certificates /etc/infinoted/infinoted-{cert,key}.pem are created with
    infinoted as owner and group.
- Enabling/disabling works and enables/disables the service
- Gobby is able to connect to the server and create a document
