tests: Only log critical errors from scapy

Since 2.4.5 scapy started issuing warnings about a few different
configurations during our tests. These are harmless, but they generate
stderr output, which upsets atf_check.

Configure scapy to only log critical errors (and thus not warnings) to
fix these tests.
