[PATCH 3/5] sandbox: add sandbox.dtb to always-y

[Masahiro Yamada]

Unlike Linux, Barebox does not support 'make dtbs_install'.
There is no good reason to use dtb-y, which is not natively
supported by the Barebox build system.

Sandbox is the special architecture that compiles DTB as a
separate file. Add .dtb to always-y directly.

CONFIG_OFTREE is a bool option. Use a more Kbuild-ish style
instead of ifeq ($(CONFIG_OFTREE),y).
