convert/svn: delegate to svn bindings if HTTP probe fails
convert extension tries to guess the remote repository type with HTTP probes.
Unfortunately, it does not handle authentication or HTTPS handshakes, so regular
svn repositories may be excluded. Instead, when a non-404 error is retrieved,
we keep trying with the svn bindings. The drawback is missing svn bindings will
make the conversion to fail even for non-svn targets. This can be avoided with
--source.
