FAI version 5.8.2~bpo9+2

[Thomas Lange]

I've created a new FAI version. This version replaces two big packages
in /etc/fai/NFSROOT with smaller replacements. emacs25-nox is replaced
by zile and dnsutils is replaced by udns-utils. This will save more
than 100MB in the nfsroot.

FAI 5.8.2~bpo9+2 is now available for stretch in the fai-project.org
repository and will include default configs for a stretch nfsroot.

FAI 5.8.2 was uploaded to unstable and includes config for creating a
buster nfsroot. This version will become available in the
fai-project.org repository for buster during the next days.
