package/libconfuse: switch to the new upstream

libconfuse is being migrated to github (see
http://www.nongnu.org/confuse/

) So, just follow suit.

Needs a bit of a hack so gettextize + autoreconf does not step on each
other's toes. See comment in the patch.

[Yann: fix gettextizing, write commit log]
