selftests/bpf: Enlarge select() timeout for test_maps

Felix Maurer requested to merge fmaurer-rh/centos-stream-9:bz2032718 into main

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2032718 Tested: Confirmed on x86_64 that the timeout is the cause of the failures. Compiled and ran the fixed test successfully.

commit 2d82d73da35b72b53fe0d96350a2b8d929d07e42 Author: Li Zhijian lizhijian@cn.fujitsu.com Date: Fri Aug 20 09:55:53 2021 +0800

selftests/bpf: Enlarge select() timeout for test_maps

0Day robot observed that it's easily timeout on a heavy load host.
-------------------
 not ok 3 selftests: bpf: test_maps # exit=1
-------------------
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.

In practice, i tried to pin it to only one cpu by 'taskset 0x01 ./test_maps',
and knew 10S is likely enough, but i still perfer to a larger value 30.
