IMAP: don't include mailbox under the virtual namespace in LIST responses.

Clients now have to use the NAMESPACE extension [RFC 2342] to discover
mailboxes under the “virtual/” namespace.  (Plus an extra LIST command,
causing an overhead two roundtrips.)  Of course the downside is that non
namespace-aware clients lose access to the “virtual/{all,flagged,…}”
mailboxes, but on second thought it's probably better this way rather
than having such clients treat these mailboxes as regular mailboxes.
