Sniffer bug: fakedns alone should not override domain for tls/http/quic (when there is no map-domain)

[patterniha]

currently, "destOverride": ["fakedns"] override domain for tls/http/quic protocol when ip is in fake-pool-range and when we have no map-domain.

This shouldn't happen and this is fakedns+others job.

///

also, it seems fakedns+others has no practical use and can be removed later.

This is a feature I developed, not a bug. I had discussion with Fangliding.

1. documentation says:
   其中 ["fakedns+others"] 相当于 ["http", "tls", "quic", "fakedns"]

But it is not equal to ["http", "tls", "quic", "fakedns"]

2. Also, documentation says:
   当 IP 地址处于 FakeIP 区间内但没有命中域名记录时会使用 http、tls 和 quic 进行匹配。

But this is not correct: #4726 (comment), #4726 (comment)

///

The documentation says two contradictory things, neither of which is correct !!!
