    Redirect stder in gdb-add-index.sh test
    
    gdb-add-index might produce an error message on stderr when trying to
    disable debuginfod support. Any message to stderr makes the testcase
    fail. This looks like a gdb bug:
    https://sourceware.org/bugzilla/show_bug.cgi?id=29316
    But it is easy to workaround by redirecting stderr to stdout.
