Mark docker-*-selinux pkgs as obsolete

These are replaced by `container-selinux` on fedora-25 and centos-7.
Marking these packages as obsolete makes the installation process a bit
smoother, otherwise the user will have to manually uninstall the older
packages to install the new one.

Also makes fedora24 use container-selinux which is now supports labeling
the `dockerd` binary correctly.
