rhel: Fix creation of symlink for ocf script

The policy is to use %files to track installed files.

If %files is not used the resulting file is not owned by any package.

Before this commit:
 # rpm -qf /usr/lib/ocf/resource.d/ovn/ovndb-servers
 file /usr/lib/ocf/resource.d/ovn/ovndb-servers is not owned by any package

After this commit:
 # rpm -qf /usr/lib/ocf/resource.d/ovn/ovndb-servers
 openvswitch-ovn-common-2.7.90-1.fc26.x86_64

Fixes: a4245b7 ("ovn: Add ovn db servers ocf script in fedora packager")
