Skip *.site_url alias only for subdomain multisites

When alias_domains contains *.site_url (e.g., *.example.com for site
example.com), skip it ONLY if the site is a subdomain multisite since
_wildcard.site_url is already added in that case. For non-multisite
sites with *.site_url alias, create the _wildcard.site_url file.
