wget: Use devel/libidn2 and adjust `idn' option logic in options.mk

Since wget-1.19, libidn2 is needed for the IDN/IRIs support. Adjust
the `idn' package option logic to reflect that and explicitly ask
for it via CONFIGURE_ARGS. This should also fix the build without
the `idn' option selected pointed out by john heasley via PR pkg/52726.
