nixos/tests/networking.*.macvlan: disable reverse path check

Browse Source 
Generated reverse path filtering rules for the macvlan interface
seem to be incorrect, causing the test to fail - sometimes or always,
depending on the dhcpcd version used.
- Disable reverse path checking temporarily to avoid blocking the channel
- Print more diagnostic information for debugging
