Revert "overlay: Camera: Use Qualcomm ZSL" and use camerawrapper instead

Camera app assumes preview doesn't stop when taking a picture using enableZSL
flag. However, our cam seems to stop preview, so we hack the parameter
inside our wrapper instead.

This reverts commit 304160fc2c06e1bb91587ebea946edce421135d4.
