selftests: forwarding: vxlan_bridge_1d: fix test failure with br_netfilter enabled
The test generates VXLAN traffic using mausezahn, where the encapsulated
inner IPv4 packet contains a zero IP header checksum. After VXLAN
decapsulation, such packets do not pass sanity checks in br_netfilter
and are dropped, which causes the test to fail.
Fix this by calculating and setting a valid IPv4 header checksum for the
encapsulated packet generated by mausezahn, so that the packet is accepted
by br_netfilter. Fixed by using the payload_template_calc_checksum() /
payload_template_expand_checksum() helpers that are only available
in v6.3 and newer kernels.
