Ignoring libraries that are on the boot module layer does not work with relative paths

[Technici4n]

Server installs use relative paths for the legacy classpath. Unfortunately, relying on deduplication doesn't work:

Exception in thread "main" java.lang.IllegalStateException: Module named cpw.mods.bootstraplauncher was already on the JVMs module path loaded from C:\Users\bruno\Downloads\test-neodev-server-5\libraries\cpw\mods\bootstraplauncher\2.0.2\bootstraplauncher-2.0.2.jar but class-path contains it at location libraries\cpw\mods\bootstraplauncher\2.0.2\bootstraplauncher-2.0.2.jar
