THRIFT-586. python: TSocket incorrectly sets the exception type when an end of file error occurs

TTransportException's type was set to "Transport not open" in some cases, which should
be its message.
Use named arguments and set the type for TTransportException to END_OF_FILE in TSocket#read
and TSocket#write.
