[JVM IR] Do not generate clinit as enclosing method.

The JVM and newer Android runtimes treats that the same as if
there is no enclosing method. However, older Android runtimes
for Android 5 and 6 throw exceptions on reflective access
and even older runtimes have different behavior. To avoid
those issues, exclude <clinit> from enclosing method attributes.
