git: DragonFly_RELEASE_3_0 pthread_join(3): If the target thread is detached, return EINVAL.

    pthread_join(3): If the target thread is detached, return EINVAL.
    
    We were returning ESRCH previously, which is wrong, as it indicates
    that the thread could not be found. Fix this in both libthread_xu
    and libc_r.
    
    See http://pubs.opengroup.org/onlinepubs/009695399/functions/pthread_join.html

    [ESRCH]
        No thread could be found corresponding to that specified by the
        given thread ID.
    
    ...
    
    [EINVAL]
        The value specified by thread does not refer to a joinable thread.
