Remove dependency on InflaterInputStream.closed field.

In upstream OpenJDK the InflaterInputStream.closed field is private.
During integration of OpenJDK into Android it was changed to be
protected so that it could be used by StrictJarFile, and in the process
was accidentally made part of the public API. This change removes the
StrictJarFile dependency on that field.
