internal/export/idna: fix verifyDNSLength option

The previous code hardwired the NonTransitional profile for
certain operations. This had the effect of erasing the
verifyDNSLength flag meaning labels were almost never checked
for proper length. Fixing this exposed various issues.

Also fixes panic for empty strings.

Updates golang/go#18567.
