[PATCH] Dockerfile: Replace unneeded backports pinning with explicit release selection

[Jan Kiszka]

From: Jan Kiszka <jan.k...@siemens.com>

Backport repos have a priority of 100 by default, thus can just be added
with extra pinning. Use explicit release selection on the installation
of qemu-user-static instead, that's simpler.
