RFR: 8352935: Launcher should not add $JDK/../lib to LD_LIBRARY_PATH [v3]

[Joachim Kern]

> In the JDK launcher, there is a codepath which would set/modify the LD_LIBRARY_PATH. This happens unconditionally on AIX and Linux/musl and can also happen on other Linux platforms if an LD_LIBRARY_PATH is pre-set which contains a libjvm.so.
> 
> The LD_LIBRARY_PATH is set to $JVMPATH:$JDK/lib:$JDK/../lib. The last part of this, $JDK/../lib, seems to be a remnant of times when there was a jre subfolder in a JDK deployment. So it should likely be removed.
