tex-babel-french: update to 3.4c

This is a bug fix release: \date shouldn't have been redefined in French.

Please note that babel-french 3.4 requires luatex 1.0 or newer to be used
with the luatex engine.

3.4a

- Both options "french" and "acadian" can now be used \ 
simultaneously
  in a document;
- New command \FBsetspaces to help customising spaces added before
  high punctuation and inside quotes;
- \FBthousandsep (used in French by numprint) is now a kern;
- babel-french now requires eTeX.
