selftests/net: packetdrill: add --mss option to three tests
Three tests are cooking GSO packets but do not provide
gso_size information to the kernel, triggering this message:
TCP: tun0: Driver has suspect GRO implementation, TCP performance may be compromised.
Add --mss option to avoid this warning.
