[PATCH 04/13] Conditionally enable transparent flow flag when connecting

[KOVACS Krisztian <hidden@sch.bme.hu>]

Set FLOWI_FLAG_ANYSRC in flowi->flags if the socket has the
transparent socket option set. This way we selectively enable certain
connections with non-local source addresses to be routed.
