s390/hvc_iucv: add simple wildcard matches to the iucv allow filter
Introduce a wildcard character to filter a range of z/VM user IDs with a single filter entry. Only the leading portion up to the wildcard of an filter entry contributes to the match. This reduces the filter size and avoids configuration updates when deploying new terminal server instances.
