>> The fix splits Linux app launcher in app launcher and launcher shared lib. App launcher is pure C and doesn't have C++ code. App launcher lib incorporates bulk of C++ code from app launcher. 
>> At startup app launcher loads launcher shared lib and calls functions it provides to get data for launching JVM (path to jli lib and arguments for JLI_Launch function call).
>> App launcher unloads launcher shared lib before launching JVM to remove C++ runtime from the process memory.
>> Getting rid of C++ code from app launcher required to rewrite app installation location lookup code from C++ to C. LinuxPackage.c source is C alternative for https://github.com/openjdk/jdk/blob/master/src/jdk.jpackage/linux/native/applauncher/Package.cpp and https://github.com/openjdk/jdk/blob/master/src/jdk.jpackage/linux/native/applauncher/Executor.cpp.

>> - `applauncherlib`: launcher lib code on Linux and launcher code on other platforms.
