KNOWN_BUGS: drop the empty error buffer entry, it no longer happens
Issue 544 asked for a failf() in the connect path and was closed in
April 2016. The call is there, but the entry stayed.

Checked against current master by reading CURLOPT_ERRORBUFFER from a
program rather than going by what the curl tool prints, and driving the
failures with CURLOPT_RESOLVE. The buffer is set every time, with one,
two, three and four addresses, for IPv4 and IPv6 alike.

The entry describes addresses that cannot be reached at all rather than
ones that time out, so the same set was run again inside a network
namespace holding only loopback and no routes, where connect() fails
immediately. That returns CURLE_COULDNT_CONNECT, which is the case the
entry names, and the buffer still holds "Failed to connect to <host>
after 0 ms: Could not connect to server".

Fixes #544
Closes #22952
