[PATCH v2 04/11] kconfig: unittest: test automatic submenu creation

[Masahiro Yamada]

If a symbols has dependency on the preceding symbol, the menu entry
should become the submenu of the preceding one, and displayed with
deeper indentation.

This is done by restructuring the menu tree in menu_finalize().
It is a bit complicated computation, so let's add a test case.

Changes in v2:
  - shorten directory name  'auto_submenu_creation' -> 'auto_submenu'
