RFR: JDK-8304063: tools/jpackage/share/AppLauncherEnvTest.java fails when checking LD_LIBRARY_PATH [v2]

[Matthias Baesken]

> The test fails on Alpine Linux 3.17, when checking the environment variable LD_LIBRARY_PATH; looks like the actual env variable is much longer than the test expects. It turned out that at least on Linux (probably also on other OS like AIX)  the actual env variable has the expected string at it's end, but might contain more path entries ( LD_LIBRARY_PATH can be adjusted by jvm - https://github.com/openjdk/jdk/blob/master/src/java.base/unix/native/libjli/java_md.c  ).
