rG9795f14ec40a: netlink: Align allocations on __max_align_t, not uint64_t.
Summary

uint64_t is not sufficient alignment for allocators on all platforms.
On a CHERI platform pointers require 16 byte alignment, but also if a
type contained a uint128_t or long double it would not be aligned
correctly either. C11 added max_align_t precisely to provide a
portable type for allocators to use.
