Certain packages still not included by debian-cd to final ISO when building Debian 9,10

[serhepopovych]

When building profiles with extended package sets certain packages are missing in final
ISO image unless explicitly listed in *.packages or *.downloads files for any profile.

Known packages are:

# required by libnet-ssleay-perl                                                                                                                     
perl-openssl-defaults                                                                                                                                
                                                                                                                                                     
# required by python-cryptography                                                                                                                    
python-cffi-backend                                                                                                                                  
                                                                                                                                                     
# required by xserver-xorg                                                                                                                           
xserver-xorg-input-all

This issue is known before #19 and thus assumed that it is unrelated to it.

[serhepopovych]

Packages not included not fetched with reprepro(1) for some unknown reason. Most (all?) these packages mentioned in Depends tag of other packages via their Provides name, not explicit package name to support alternatives.

[serhepopovych]

Issue with xserver-xorg-input-all and xserver-xorg-video-all now fixed in debian-cd master
and backported to mydistro/buster and mydistro/stretch branches of our debian-cd repository. In simple-cdd-meta this accepted with debian-cd submodule update in
3df62a1.

[serhepopovych]

Other issues most likely related to virtual package handling bugs in simple-cdd and should be fixed in current version
of simple-cdd (e.g. in bullseye). However that isn't tested yet, so keep this issue open.
