Subject: [PATCH v06 15/36] uapi linux/socket.h: include sys/socket.h in user space

This libc header has sockaddr definition in user space.

Fixes user space compilation errors like these from kernel headers including
only linux/socket.h:

error: field ‘ifru_addr’ has incomplete type
struct sockaddr ifru_addr;
error: field ‘_sockaddr’ has incomplete type
struct sockaddr  _sockaddr;
error: invalid application of ‘sizeof’ to incomplete type ‘struct sockaddr’

With this following uapi headers now compile in user space:

rdma/rdma_user_rxe.h
linux/vm_sockets.h
linux/ncp_fs.h
linux/nfc.h
linux/phonet.h
