tools/jpackage/share/AppLauncherEnvTest.java fails with dynamically linked libstdc++

Origin: upstream, https://github.com/openjdk/jdk/commit/78a8a99d990dcc0b77c096bb2ca2c1bb86462e3f
Bug: https://bugs.openjdk.org/browse/JDK-8312488
Reviewed-By: asemenyuk, almatvee
Last-Update: 2024-07-18

The generated image contains libjpackageapplauncheraux.so that
contains a destructor function dcon(). It calls already disposed
logger, causing a crash.
