The following warning occurs from commit "boot/uboot: allow taking the
entire default environment from a text file".

  boot/uboot/Config.in:141:warning: config symbol
  'BR2_TARGET_UBOOT_DEFAULT_ENV_FILE' uses select, but is not bool or
  tristate

Add a hidden 'bool' config so we can enable dependencies.

In addition, the DEFAULT_ENV_FILE works by setting Kconfig options,
therefore we also need to depend on
BR2_TARGET_UBOOT_BUILD_SYSTEM_KCONFIG.
