Fix "Operator Vendor String Test"

CVP is reporting a warning[1] when testing the EAP Operator:

Error verifying vendor string: hudson.AbortException: Support name should be 'Red Hat', got: 'WildFlyServer'

The issue seems to be related to the CSV file where the `support` field value is `WildFlyServer` at https://github.com/jbossas/eap-operator-packaging/blob/master/release-operator/manifests/1.0.0/eap-operator.v1.0.0.clusterserviceversion.yaml#L12

I erroneously thought this field was about the type supported by the operator while it means the entity (company, open source org) that support the operator.

This field value must be set to "Red Hat" instead.
