[Fix]

second timeout per test") for default timeout added since Bionic.

[Original Bug Report]
These 3 tests will fail with timeout when running the whole "net" test in
ubuntu_kernel_selftests:
* not ok 12 selftests: net: xfrm_policy.sh # TIMEOUT
* not ok 16 selftests: net: pmtu.sh # TIMEOUT
* not ok 19 selftests: net: udpgso_bench.sh # TIMEOUT
However they will pass if you run them manually.
So there must be some test in net that will cause this.
From the test result it looks like the test was executed in the following
sequence:
ok 1 selftests: net: reuseport_bpf
ok 2 selftests: net: reuseport_bpf_cpu
ok 3 selftests: net: reuseport_bpf_numa
ok 4 selftests: net: reuseport_dualstack
# Successok 5 selftests: net: reuseaddr_conflict
ok 6 selftests: net: tls
ok 7 selftests: net: run_netsocktests
ok 8 selftests: net: run_afpackettests
ok 9 selftests: net: test_bpf.sh
ok 10 selftests: net: netdevice.sh
ok 11 selftests: net: rtnetlink.sh
not ok 12 selftests: net: xfrm_policy.sh # TIMEOUT
not ok 13 selftests: net: test_blackhole_dev.sh # exit=1
ok 14 selftests: net: fib_tests.sh
ok 15 selftests: net: fib-onlink-tests.sh
not ok 16 selftests: net: pmtu.sh # TIMEOUT
ok 17 selftests: net: udpgso.sh
not ok 18 selftests: net: ip_defrag.sh # exit=255

not ok 21 selftests: net: msg_zerocopy.sh # exit=1
ok 22 selftests: net: psock_snd.sh
ok 23 selftests: net: udpgro_bench.sh
ok 24 selftests: net: udpgro.sh
