RFR: 8293806: JDK_JAVA_OPTIONS picked up twice if LD_LIBRARY_PATH is set

[Dmitry Samersoff]

If the user has set LD_LIBRARY_PATH to use a particular libjvm.so, options from the JDK_JAVA_OPTIONS environment variable are picked up twice.

If an option cannot be accepted twice (e.g., -agentlib), the application fails to start.

The same happens on operating systems that doesn't support $RPATH/$ORIGIN and always have to set LD_LIBRARY_PATH and re-exec the launcher.

The fix adds one additional argument - orig_argv to JLI_Launch() and use it in on relaunch in execv() call.

All relevant jtreg tests are passed.
