    PR28240: debuginfod client root-safe negative caching

    Negative cache (000-permission) files were incorrectly treated as
    valid cached files for the root user, because root can open even
    000-perm files without -EACCES.  Corrected this checking sequence.

    Fixed the debuginfod testsuite to run to completion as root or
    as an ordinary user, correcting corresponding permission checks:
        stat -c %A $FILE
    is right and
        [ -w $FILE]  [ -r $FILE ]
    were wrong.
