netlink: specs: add big-endian byte-order for u32 IPv4 addresses 



The fix commit converted several IPv4 address attributes from binary
to u32, but forgot to specify byte-order: big-endian. Without this,
YNL tools display IPv4 addresses incorrectly due to host-endian
interpretation.

Add the missing byte-order: big-endian to all affected u32 IPv4
address fields to ensure correct parsing and display.

Fixes: 1064d521 ("netlink: specs: support ipv4-or-v6 for dual-stack fields")
