fingerprint: Fix section extraction using 'dump_fmap'
Previously, '/dev/stderr' was passed to 'dump_fmap' and it was
interpreted as a section. It was obviously wrong, but it worked because
'dump_fmap' silently ignored missing sections.
CL:5408907 fixed that behavior. Now 'dump_fmap' fails if section was not
found, which showed the problem.
