Subject: [PATCH bpf] samples: bpf: fix test_lru_dist

From: Matteo Croce <mcroce@...rosoft.com>

Fix this build error:

  CC  samples/bpf/test_lru_dist
samples/bpf/test_lru_dist.c:36:8: error: redefinition of ‘struct list_head’
   36 | struct list_head {
      |        ^~~~~~~~~

This happens even after running `make headers_install`
