openshift: move pipeline sa bounded scc back to anyuid
openshift: move pipeline sa bounded scc back to anyuid

Set the scc bound to `pipeline` (default sa) back to `anyuid` from `restricted.

This change is necessary as ClusterTasks shipped with the operator (buildah, s2i...) are
failing with the following error.

```bash
[build : build] level=error msg="Error while applying layer: ApplyLayer exit status 1 stdout: stderr: there might not be enough IDs available in the namespace (requested 0:12 for /var/spool/mail): lchown /var/spool/mail: invalid argument"
[build : build] error creating build container: Error committing the finished image: error adding layer with blob "sha256:a6b97b4963f5ace479dbf5bdc821bdb757de2aef502a39a19b236856827250d0": ApplyLayer exit status 1 stdout: stderr: there might not be enough IDs available in the namespace (requested 0:12 for /var/spool/mail): lchown /var/spool/mail: invalid argument
```
