Rephrase the log messages emitted if the TestSocks check is positive

Previously Tor would always claim to have been given a hostname
by the client, while actually only verifying that the client
is using SOCKS4A or SOCKS5 with hostnames. Both protocol versions
allow IP addresses, too, in which case the log messages were wrong.

Fixes #4094.
