Current separation of part of the logic into include_path obscures the purpose of Dirs (see expand_file_names). Moreover for each particular Erl its source file was included twice in Dirs, which is now corrected. Also InclDirs (specified in erl_opts) as part of erlcinfo since they can affect resulting graph, which needs to be therefore regenerated when InclDirs change. See added test as an example.
