Bug#987124: console-setup not work properly with plymouth

[Vladimir K]

If plymouth password prompt is used during boot (i.e. root volume decryption 
from initramfs), just the patch above will not work, also need to add 
plymouth-quit.service to 'After' property in console-setup.service

A bit more refined variant without ps:

Check if systemd is present to avoid errors if it is not.

Other than that I do not know how to quickly detect exited plymouth and 
properly order console-setup launch in a SysV boot.
Maybe modify /etc/init.d/console-setup.sh to hold while plymouthd is running 
(with a timeout).

Still reproducible on testing.

Here is the deal:
Console setup is supposed to rely on cached scripts in /etc/console-setup 
(copied to initramfs). But plymouth starts in initramfs, occupies tty1, which 
causes setupcon to detect graphical mode and skip tty1.
When scripts exist in /etc/console-setup, conditions in 
/lib/console-setup/console-setup.sh basically skip running setupcon if 
console-setup.service is launched first time during boot.

To fix this:
1. add plymouth-exit.service to After= in console-setup.service
2. add plymouth exit detection to console-setup.sh

The /etc/init.d/console-setup.sh startup script does not change
