[compiler-rt] [NFC][asan] Try to deflake asan_lsan_deadlock test (PR #137718)

[Vitaly Buka via llvm-commits]

https://github.com/vitalybuka created https://github.com/llvm/llvm-project/pull/137718

10s looks not enough. With highly parallel test
execution on VMs it's very possible that Asan
report will have no enough time to produce output.

I can reproduce locally 1s is not always enough,
but likely my workstation is faster then buildbot.

Additionally, don't use puts/CHECK to validate
timeout. We can exit with 0 and it should violate
"not" expectation.
