bpf: guard BPF_NO_PRESERVE_ACCESS_INDEX in skb_pkt_end.c
This little patch is a follow-up to:
https://lore.kernel.org/bpf/20240507095011.15867-1-jose.marchesi@oracle.com/T/#u
The temporary workaround of passing -DBPF_NO_PRESERVE_ACCESS_INDEX
when building with GCC triggers a redefinition preprocessor error when
building progs/skb_pkt_end.c. This patch adds a guard to avoid
redefinition.
