THRIFT-5214: Use peek to implement socket connectivity check

Client: go

In previous implementation of socket connectivity check, we try to read
1 byte and put it into buffer when succeeded. The buffer complicates
the implementation of Read function. Change to use syscall.Recvfrom with
MSG_PEEK flag instead so that the buffer is no longer needed.
