    af_unix: selftest: Fix the size of the parameter to connect()
    
    [ Upstream commit 7d6ceeb1875cc08dc3d1e558e191434d94840cd5 ]
    
    Adjust size parameter in connect() to match the type of the parameter, to
    fix "No such file or directory" error in selftests/net/af_unix/
    test_oob_unix.c:127.
    
    The existing code happens to work provided that the autogenerated pathname
    is shorter than sizeof (struct sockaddr), which is why it hasn't been
    noticed earlier.
    
    Visible from the trace excerpt:
    
    bind(3, {sa_family=AF_UNIX, sun_path="unix_oob_453059"}, 110) = 0
    clone(child_stack=NULL, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x7fa6a6577a10) = 453060
    [pid <child>] connect(6, {sa_family=AF_UNIX, sun_path="unix_oob_45305"}, 16) = -1 ENOENT (No such file or directory)
    
    BUG: The filename is trimmed to sizeof (struct sockaddr).
