Tsl2561_Example: Removed duplicate Tsl2561_Example

It appears that an additional tsl2561 Java example existed.
Removed the *newer* Tsl2561_Example.java in favor of the original
example.  Updated all corresponding collateral which references the
Tsl2561_Example.java file (CMake and library descriptor file).
