lib: Fix class and namespace usage

The (dummy) init_lib function was linking correctly only due to a
namespace 'collision' adding the init_lib to libcamera namespace, which
is 'shared' by class libcamera.

The init function was designed to be a class member function of the
libcamera object - and is used as such in the existing test function.

Instead of relying on the namespace collision - update the lib/main.cpp
example file to correctly utilise the class header - and specify the
function declaration, so that further implementations do not fall into
the same bad habits.
