Bug#887501: systemctl status should not use --pager

[Guido Günther]

Package: init-system-helpers
Version: 1.51
Severity: normal
Tags: patch

Hi,
systemctl status should be invoked with --no-pager, otherwise it might
hang on non-interactive command. This was observed running serverspec's

   describe service('systemd-timesyncd') do
     it { should be_running }
   end

Possible patch attached.
Cheers,
 -- Guido
