Tests: adjusted mail_smtp.t "long pipelined" TODO.
Prior to fixed reading with fully filled buffer in 2851e4c7de03 (1.21.0),
test for long pipelined commands leads to connection close by nginx, which
can result in RST and no response seen by the client, notably on win32.
While here, cleaned up permitted smtp_auth methods in that particular server.
