Bug#1116288: sysvinit-core: consider depending on login

[Chris Hofstaedtler]

Package: sysvinit-core
Version: 3.15-2

Hello Mark,

I believe sysvinit starts gettys and (possibly indirectly) login.
If this is the case, when sysvinit 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
