security: wildcards for superusers includes the security index

The superuser role is the only user assignable role that grants access to the .security index, but when
resolving wildcards the index was not getting resolved. The resolution of indices and aliases explicitly
excludes the .security index for users that are not the internal user without checking if the user has the
superuser role. This commit adds a check in for the superuser role.
