Remove defunct DNS seed entries (#309)

Browse source 
Both Lightning DNS seeds are no longer operational: lseed.bitcoinstats.com
returns SERVFAIL and lseed.darosior.ninja is confirmed dead by its
maintainer. The empty seed list is handled gracefully with a warning
log. Retained the original IRC discussion as historical context for future seed
selection.
