Deleting unused or broken files

The tests removed from luni/src/test are testing files that no
longer exist. It's possible that they provided some coverage of
the code which is not provided for the OpenJDK code.

The classes removed from ojluni/src/main are the ones not
explicitly mentioned in the openjdk_java_files.mk.
