samples: bpf: Don't fail for a missing VMLINUX_BTF when VMLINUX_H is provided
[ Upstream commit ec24704492d8791a52a75a39e3ad762b6e017bc6 ]
samples/bpf build currently always fails if it can't generate
vmlinux.h from vmlinux, even when vmlinux.h is directly provided by
VMLINUX_H variable, which makes VMLINUX_H pointless.
Only fails when neither method works.
Fixes: 384b6b3bbf0d ("samples: bpf: Add vmlinux.h generation support")
