[PATCH] conf: No routable interface for IPv4 or IPv6 is informational, not a warning

[Stefano Brivio <sbrivio@redhat.com>]

...Podman users might get confused by the fact that if we can't
find a default route for a given IP version, we'll report that as a
warning message and possibly just before actual error messages.

However, a lack of routable interface for IPv4 or IPv6 can be a
normal circumstance: don't warn about it, just state that as
informational message, if those are displayed (they're not in
non-error paths in Podman, for example).
