RFR: 8350214: Test gtest/AsyncLogGtest.java fails after JDK-8349755 [v2]

[Johan Sjölen]

> Hi,
> 
> [8349755](https://bugs.openjdk.org/browse/JDK-8349755) introduced a bug in debug builds when running with `-Xlog:async -Xlog:all=debug`. Specifically, this will cause UL to select for `deathtest` and `deathtest2`, which should only be selected when explicitly asked for.
> 
> In order to fix this, I've added a small debug-only snippet which ensures that any wildcard selector does not select `deathtest` or `deathtest2`. I've also added a testcase in order to catch this regression.
