elm_conform: Remove legacy to coraborate with current indicator properly

elm_conform has had two indivisual indicators for each rotation angle.
However elm_conform don't have to have two indicator as tizen 2.4 did,
because indicator server daemon structure has been changed.

And current legacy logic on conform makes problem on the indicator server.
This commit removes legacy logic to coraborate with current indicator server properly
