[PATCH 1/2] test_server: test_early_hints: fix test reliability

[Eric Wong <bofh@yhbt.net>]

IO#sysread may only capture the 103 response and return before
the server can send the 200.  Since we don't support persistent
connections, we can just use IO#read to rely on the server
giving us an EOF after the 200 is sent.
