Add openssh to rebootstrap

[Samuel Thibault <sthibault@debian.org>]

Hello,

Arguably, working on bootstrapping a new arch really wants having ssh
server available. openssh happens to provide a nognome build profile
that makes it easy to build early, as the attached patch does, available
on my repo

git@salsa.debian.org:sthibault/rebootstrap.git

as 8691e727d58c4ea8b4d85deeca114ffb1c9b2a8d

One notable thing is that openssh assumes that libc-dev pulls
libcrypt-dev, which the unstaged libc-dev does not do, but after the
first automatically_cross_build_packages run we do have libcrypt-dev
built so we can meet this requirement easily without adding another
glibc stage just for the dependency.

    Add openssh
    
    It notably assumes that libc-dev pulls libcrypt-dev, which the unstaged
    libc-dev does not do, but after the first automatically_cross_build_packages
    run we do have libcrypt-dev built so we can meet this requirement easily
    without adding another glibc stage just for the dependency.
