bpo-35031: Fix test_start_tls_server_1 on FreeBSD buildbots (GH-10011)

Some FreeBSD buildbots fail to run this test as the eof was not being received by the server if the size is not big enough. This behaviour only appears if the client is using TLS1.3.
(cherry picked from commit f6a47f3e316cede2a07a1f74a509f6d80ab8fef0)
