[PATCH 39/98] include/uapi/linux/socket.h: include sys/socket.h in userspace

This libc header has sockaddr definition for userspace.

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

error: field ‘ifru_addr’ has incomplete type
struct sockaddr ifru_addr;
