Fix for https://bugs.openjdk.java.net/browse/JDK-8254702

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/app... and https://github.com/openjdk/jdk/blob/master/src/jdk.jpackage/linux/native/app....

Layout of jpackage's native code changed: - `common`: code shared between all jpackage binaries. - `applauncher`: launcher only code. - `applauncherlib`: launcher lib code on Linux and launcher code on other platforms. - `applaunchercommon`: code shared between launcher and launcher lib on Linux and launcher code on other platforms.
