bitbake: doc: mention that addtask handles multiple dependencies

Add a note explaining that "addtask" can accept multiple dependencies,
just in case someone runs across such an example and is confused.

+.. note::
+
+   While it's infrequent, it's possible to define multiple tasks as
+   dependencies when calling ``addtask``. For example, here's a snippet
+   from the OpenEmbedded class file ``package_tar.bbclass``::
+
+     addtask package_write_tar before do_build after do_packagedata do_package
+
+   Note how the ``package_write_tar`` task has to wait until both of
+   ``do_packagedata`` and ``do_package`` complete.
