d/patches: Apply init_buildsystem hostname patch
requested to merge adalessandro/obs-build:wip/adalessandro/T7859-init_buildsystem-missing-patch into collabora/master
Task https://phabricator.apertis.org/T7859
Commit 3e1052b3 ("init_buildsystem: Move hostname ip entry to the end of /etc/hosts") directly modified the source by mistake.
Commit c4707ab4 ("Reapply 3e1052b3 as a patch") fixed this by applying the change as a debian patch, but missed the entry in d/p/series.
This commit adds the missing entry to d/p/series, so the patch is properly applied.
