Make libidn optional in wget.

wget will find and use libidn if it is present, which uses gettext.
This dependency was not captured in the wget formula.

To keep things simpler, the user must now opt-in to libdin by brewing
with "--enable-iri". Without this flag, we tell configure not to look
for libidn.

Fixes #1105.
