console_systemd: remove the timeout when using 'systemd-ask-password'

Without this, the password request will expire after 90 seconds leaving
no way to provide the password without OpenVPN asking for it again.
Given that interactive use will wait for input without a timeout, it
makes sense to have non-interactive usage also wait until the user is
ready instead of forcing users to race against the timeout.
