Bug#1116286: systemd-sysv: consider depending on login

[Chris Hofstaedtler]

Package: systemd-sysv
Version: 258-1

Hi,

I believe systemd starts gettys and (possibly indirectly) login. 
If this is the case, when systemd acts as the running init to manage 
these, please have it ensure the `login` package is installed. Note 
that login is not essential anymore.

At a later date I'm considering moving getty/agetty into the login 
package, too.

Thanks,
Chris
