tools/bpf: fix test_sockmap failure
On one of our production test machine, when running
bpf selftest test_sockmap, I got the following error:
# sudo ./test_sockmap
libbpf: failed to create map (name: 'sock_map'): Operation not permitted
libbpf: failed to load object 'test_sockmap_kern.o'
libbpf: Can't get the 0th fd from program sk_skb1: only -1 instances
......
load_bpf_file: (-1) Operation not permitted
ERROR: (-1) load bpf failed
The error is due to not-big-enough rlimit
struct rlimit r = {10 * 1024 * 1024, RLIM_INFINITY};
The test already includes "bpf_rlimit.h", which sets current
and max rlimit to RLIM_INFINITY. Let us just use it.
