Remove unused reference to missing sun.misc.Unsafe method

The copyMemory(byte[], long, byte[], long, long) method doesn't exist
in sun.misc.Unsafe in Android, and leaving the dangling reference
causes soft-verification errors when a jarjar'd version of
libprotobuf-java-lite is included in the bootclasspath:
 Soft verification failures in void com.android.framework.protobuf.UnsafeUtil.copyMemory(byte[], long, byte[], long, long)
 void com.android.framework.protobuf.UnsafeUtil.copyMemory(byte[], long, byte[], long, long): [0x7] couldn't find method sun.misc.Unsafe.copyMemory ([BJ[BJJ)V

This method is unused in the current open-source implementation of the
protobuf lite runtime, so just remove it for now.
