fdo#46102: Fix Java script examples after gbuild'ification
...they contained no class files anymore, due to missing gb_Jar_set_packageroot
calls. However, those calls only work for subdirectories, i.e., the example
.java files need to be put into a package (I chose
org.libreoffice.example.java_scripts) for all of them). This in turn required
adaption of the parcel-descriptor.xml files; not sure what the logicalname
entries there are good for if anything -- the macro names at "Tools - Macros -
Run Macro..." now unfortunately(?) contain the fully qualified paths for the
HelloWorld, HighlightText, and MemoryUpdate examples. There are additional
examples at scripting/examples/java/ that apparently do not get packaged (but I
adapted them anyway).
