Correct the access log format (#24085)

The default access log format has been unnecessarily escaped, leading to
spurious backslashes appearing in log lines.

Additionally, the `RemoteAddr` field includes the port, which breaks
most log parsers attempting to process it. I've added a call to
`net.SplitHostPort()` attempting to isolate the address alone, with a
fallback to the original address if it errs.
