Bug 6537 [SIGNED-OFF] follow-up = removing non specific lines for french unimarc

There were some lines in the specific french sysprefs that were not french/unimarc specific at all
I've removed them, the file now only contains french & unimarc specific things

I also have removed NoZebra as it's deprecated, so should not be here anymore
