wwwlisting: fix grep call for match=domain filtering

The grep call in list_match_domain_i returns true for all inboxes,
even ones without a URL that matches the regular expression, because
the qr value passed to grep is not surrounded by slashes.  Add them.

Fixes: 1988d730c0088e8b (config: support multi-value inbox.*.*url)
