The name clash is not caused directly by luainputenc, but by
luatex.sty which is loaded by luatexbase. Anyways, Herbert is
correct: there is no justification for luainputenc there, so best
file a bug report against whatever tool inserts it.

Now, to the actual problem, since it will occur with most other
Luatex specific packages: running

  sed -i 's/setattribute/setectaartattribute/g' ectaart.cls

will fix the class file.

Best regards,
Philipp
