    linux(4): Use linux_tdfind() in get_robust_list.
    
    In the Linux emulation layer linux_tdfind() has a special purpose to
    handle glibc specific TID mangling and we should use it instead of tdfind().
    
    MFC after:              2 weeks
    
    (cherry picked from commit c8e9d2b7eb6ef55e1386150458c58e6554762166)
