[PATCH net-next] samples/bpf: fix include path

[Alexei Starovoitov]

Fix the following build error:
HOSTCC  samples/bpf/test_lru_dist.o
../samples/bpf/test_lru_dist.c:25:22: fatal error: bpf_util.h: No such file or directory

This is due to objtree != srctree.
Use srctree, since that's where bpf_util.h is located.

Fixes: e00c7b216f34 ("bpf: fix multiple issues in selftest suite and samples")
