parse resource name before removing deleted secret

Although unlinking deleted secrets from a serviceaccount is currently
supported, `oc secret unlink` failed to unlink a deleted secret if its
name was specified as secrets/deleted-secret-name.

This patch parses each secret's name, removing the <secrets/> segment
before appending it to a string set of removed secret names.
