Bug 16554: Fix fr-FR sample files

Needs Bug 13669

Rewrite autorites_norme_unimarc.sql to
use only one INSERT IGNORE.

New load method complains about duplicate keys,
and both auth files are mandatory!

Also removed blank space from sample_labels.sql

Tested with unimarc_complet and all sample files.

To test
1) Apply the patch
2) Try fr-FR web installer, unimarc_complet + all sample files
There must be no errors

Don't know if fr-FR marc21 and unimarc_lecture_pub are used,
need a look from french users.
