ssl_server: Allow the client to close the connection first

Browse Source 
This is necessary when testing against OpenSSL 1.0.2g.

In the server, flush more often. Otherwise, when stdout is redirected to a
file, the server gets killed before it writes important information, such as
the logs that we expect in the test cases.
