py3: replace file() with open() in test-mactext.t

file() is not present in Python 3.
This patch also adds a b'' prefix to make sure we write bytes in Python 3.

>=0.9.1 clients send a "hello" + "between" for the null range as part of handshake.
Server should reply with capabilities and should send "1\n\n" as a successful
reply with empty response to the "between".
