    linux(4): Fix clock_nanosleep return value for unsupported clockid.
    
    The Linux clock_nanosleep() returns ENOTSUP for CLOCK_THREAD_CPUTIME_ID.
    This silence one of the LTP clock_nanosleep tests.
    
    MFC after:      2 weeks
    
    (cherry picked from commit 66e73ce7371b717b8dd0dfd6e3deeacfa95e6f8b)
