fix(rbac): missing clusterrolebinding permission

[claudio4j]

When camel-k-operator is installed in global mode, pkg/install/knative.go wants to patch a ClusterRoleBinding, but it fails with

Cannot bind the Knative addressable resolver aggregated ClusterRole: skipping
Error while binding the Knative Addressable resolver aggregated ClusterRole",
  "error":"clusterrolebindings.rbac.authorization.k8s.io \"camel-k-operator-addressable-resolver\" is forbidden: User \"system:serviceaccount:cmiranda-ops:camel-k-operator\" cannot patch resource \"clusterrolebindings\" in API group \"rbac.authorization.k8s.io\" at the cluster scope"}

There is a missing permission to patch it.

$ k auth can-i -A patch clusterrolebindings.rbac.authorization.k8s.io --as=system:serviceaccount:cmiranda-ops:camel-k-operator
no

Release Note

NONE

@claudio4j I think there should be an E2E test that captures the failing case so that it won't regress. Is it possible to create one?
