defaultenv: Reorder overlay append order ...

The defaultenv_add_base() functions adds the enviroment coming from
CONFIG_DEFAULT_ENVIRONMENT_PATH. But this is not only for
traditional enviroments, but also for external enviroments in e.g. build
systems. The external enviroment should override the enviroment set
in the board file and not the other way around. Made sure that
external enviroment is always added last.

EFI: add missing include ...

Otherwise building produces these warnings:
[...]
arch/efi/efi/efi-image.c:48:2: warning: implicit declaration of function 'read_file' [-Wimplicit-function-declaration]
arch/efi/efi/efi-image.c:48:6: warning: assignment makes pointer from integer without a cast [enabled by default]
[...]

And bootm fails for x86_64. The implicit declaration has an int as return
value, so half of the returned address is lost.
