kr.csv: remove defunct sites

[revi]

1. blog.daum.net: service discontinued
2. egloos.com: service discontinued
3. ilwar.com: redirects to founder's personal website with no mention of the site, likely discontinued
4. myhome.naver.com: site says 'discontinued @ 2008'
5. 11st.cco.kr: most likely typo.

I have some suggestions for new domains to track but it probably deserves a new PR (and maybe some discussions?) so skipping here.

[revi]

Note: A query for blog.daum.net result in NXDOMAIN and A query for egloos.com result in SERVFAIL.

Thanks so much @revi! I am merging the PR now 🙏
