CMakeLists.txt: fix warnings when using upstream boards in out-of-tree configs

Browse Source 
When we use upstream board as a target in out-of-tree board configurations we
should not link dummy/Kconfig with a board Kconfig otherwise this file is
included twice which cause cmake warnings.

For example, when out-of-tree configuration is like this:

  CONFIG_ARCH_BOARD_CUSTOM=y
  CONFIG_ARCH_BOARD_CUSTOM_DIR="boards/arm/stm32/b-g431b-esc1/"
  CONFIG_ARCH_BOARD_CUSTOM_DIR_RELPATH=y
  CONFIG_ARCH_BOARD_CUSTOM_NAME="b-g431b-esc1"

this results with many warnings during configuration stage:

  CMake Warning at cmake/nuttx_kconfig.cmake:171 (message):
