debuginfod: Don't format clog using 'right' or 'setw(20)'.

Keep the logs just plain unformatted text.

This really is a workaround for an apparent bug with gcc 8.3
-fsanitizer=undefined on arm32, which complains about the
'right' formatter:

debuginfod.cxx:3472:12: runtime error: reference binding to
misaligned address 0x00561ec9 for type '<unknown>', which
requires 2 byte alignment
