JVM Module name is changed for libraries

[kuanyingchou]

Not sure if it's intended and this happens in both KSP1 and KSP2. The module name of libraries become "$Library for XXX" if it's not specified with "-module-name" with a name other than "main" while compiling. So internal function names in libraries become, say, "f$$Library for main" instead of "f$main".
