osmo_io: Support detecting non-blocking connect()

libosmo-netif does a non blocking connect(), which as per definition of
 the socket API is signalled from the OS to the user by marking the file
descriptor writable.

osmo_io needs to signal this somehow. Previously osmo_io would only call
the write_cb if actual data has been sent. This patch changes the behaviour
so that calling osmo_iofd_write_enable() will call write_cb() on a writable
socket even if the write queue is empty.
