[class-parse] Ignore module-info.class file. (#1093)

Context: https://repo1.maven.org/maven2/org/jetbrains/annotations/24.0.1/annotations-24.0.1.jar
Context: #1096

Some AndroidX packages contain a file called `module-info.class` that
uses unsupported `.class` constructs.  It contains metadata for
[Java Modules][0].

![image](https://user-images.githubusercontent.com/179295/229861846-cbd04239-9d7b-470b-ae6c-844713009104.png)

`class-parse` emits this XML fragment for `module-info.class`:

	<package
	    name=""
	    jni-name="">
	  <class
	      abstract="false"
	      deprecated="not deprecated"
	      final="false"
	      name="module-info"
	      jni-signature="Lmodule-info;"
	      source-file-name="module-info.java"
	      static="false"
	      visibility="" />
	</package>

When we try to process this `<class/>`, `generator` emits the warning:

	warning BG8605: The Java type '' could not be found (are you missing a Java reference jar/aar or a Java binding library NuGet?)

This is neither useful nor actionable.

Ignore this file in `class-parse`, until we can properly parse it.
