selftests/bpf: Fix a selftest compilation error
When building the kernel and selftest with clang compiler (llvm17 or llvm18),
I hit the following compilation failure:
In file included from progs/test_lwt_redirect.c:3:
In file included from /usr/include/linux/ip.h:21:
In file included from /usr/include/asm/byteorder.h:5:
In file included from /usr/include/linux/byteorder/little_endian.h:13:
/usr/include/linux/swab.h:136:8: error: unknown type name '__always_inline'
136 | static __always_inline unsigned long __swab(const unsigned long y)
| ^
/usr/include/linux/swab.h:171:8: error: unknown type name '__always_inline'
171 | static __always_inline __u16 __swab16p(const __u16 *p)
...
bpf_helpers.h file provided a definition for __always_inline.
Putting 'ip.h' after 'bpf_helpers.h' fixed the issue.
