net/ipv4: Fix linux/in.h header dependencies

__DECLARE_FLEX_ARRAY is defined in include/uapi/linux/stddef.h but
doesn't seem to be explicitly included from include/uapi/linux/in.h,
which breaks BPF selftests builds (once we sync linux/stddef.h into
tools/include directory in the next patch). Fix this by explicitly
including linux/stddef.h.

Given this affects BPF CI and bpf tree, targeting this for bpf tree.

Fixes: 5854a09b4957 ("net/ipv4: Use __DECLARE_FLEX_ARRAY() helper")
