samples/bpf: check before defining offsetof

Fixes the following warning

samples/bpf/test_lru_dist.c:28:0: warning: "offsetof" redefined
 #define offsetof(TYPE, MEMBER) ((size_t)&((TYPE *)0)->MEMBER)

In file included from ./tools/lib/bpf/bpf.h:25:0,
                 from samples/bpf/libbpf.h:5,
                 from samples/bpf/test_lru_dist.c:24:
/usr/lib/gcc/x86_64-redhat-linux/6.3.1/include/stddef.h:417:0: note: this is the location of the previous definition
 #define offsetof(TYPE, MEMBER) __builtin_offsetof (TYPE, MEMBER)
