net: ipv6: allow choosing optimistic addresses with use_optimistic

The use_optimistic sysctl makes optimistic IPv6 addresses
equivalent to preferred addresses for source address selection
(e.g., when calling connect()), but it does not allow an
application to bind to optimistic addresses. This behaviour is
inconsistent - for example, it doesn't make sense for bind() to
an optimistic address fail with EADDRNOTAVAIL, but connect() to
choose that address outgoing address on the same socket.
