Subject: [PATCH] Fix build error of IPPROTO_TCP on android

I got the following error when build this lib by source on android:

```
easywsclient.cpp:522:24: error: use of undeclared identifier 'IPPROTO_TCP'
    setsockopt(sockfd, IPPROTO_TCP, TCP_NODELAY, (char*) &flag, sizeof(flag)); // Disable Nagle's algorithm
                       ^
1 error generated.
```

Add a header `#include <netinet/in.h>` fixed it.
