commit c21ca2a696c03ff3f3931768a3ada234eebf6337

    nptl: Use <support/check.h> facilities in tst-setuid3
    
    Remove local FAIL macro in favor to FAIL_EXIT1 from <support/check.h>,
    which provides equivalent reporting, with the name of the file and the
    line number within of the failure site additionally included.  Remove
    FAIL_ERR altogether and include ": %m" explicitly with the format string
    supplied to FAIL_EXIT1 as there seems little value to have a separate
    macro just for this.
