    Correct includes for unlockiter.c
    
    Some platforms (e.g., Solaris) need a declaration of memset() for the
    FD_ZERO() macro to work, contrary to POSIX standards.  Add an
    inclusion of <string.h> to accommodate them.  Also add <sys/time.h>,
    possibly needed by some older platforms, and remove a spurious
    inclusion of <sys/socket.h>.
