Subject: [PATCH] selftests/bpf: enlarge timeout to 3 seconds for test_maps

0Day robot observed that it's easily timeout on a heavy load host.

 # Failed sockmap unexpected timeout
 not ok 3 selftests: bpf: test_maps # exit=1
 # selftests: bpf: test_lru_map
 # nr_cpus:8
-------------------
Since this test will be scheduled by 0Day to a random host that could have
only a few cpus(2-8), enlarge the timeout to avoid a false NG report.
