sets LC_ALL var

the lack of a proper locale set breaks
postgres installation (default database cluster
is not created).

There are some discussions on the issue here:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=510658

I got this issue running chef-client on linode on a 11.10 ubuntu server (64bits).

You might want to extend my hack to make it configurable in some way, or you can sugest me how to do it :)
