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

[Mikko Rapeli]

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 âifru_addrâ has incomplete type
struct sockaddr ifru_addr;
error: field â_sockaddrâ has incomplete type
struct sockaddr  _sockaddr;
error: invalid application of âsizeofâ to incomplete type âstruct sockaddrâ

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
