In some cases like upgrade to -backports don't update all deps correctly causing issues. I already had in past, doing for example: sudo apt -t buster-backports install freerdp2-x11 and latest times I workaround it with: sudo apt -t buster-backports install freerdp2-x11 libfreerdp-client2-2 libfreerdp2-2 libwinpr2-2
This commit solve this issue adding binary version dependency on any component (not only for x11 client but also wayland client, server and other components used by other software, for example remmina). Also avoided to add duplicate entries (if already present in other deps of the component)
Closes: #964147
Note: I not tested it, I probably will not have enought time until weekend for do a testing build and test upgrade for all cases
