aja: Increment aja-source version for buffering setting

Add aja-source version 2 to differentiate buffering settings, which is
implemented in a255b0f74.
To register two versions, remove to return obs_source_info and register
the source inside aja-source.cpp.
Also revise aja-output.cpp to register aja-output to keep consistency of
function type.
