sshd dependancy to systemd and attack surface

Hello,

sshd has a dependancy to systemd, and thus includes a lot of libraries,
which augments its attack surface.

The recent xz-utils issue [1] has lead to this post by someone suggesting
(with a patch, apparently) to confine the sshd -> systemd dependancy
in a subprocess [2].

Maybe you want to look into it?

Thank you.
