[U-Boot] [PATCH] Makefile: fix newline escaping for CONFIG_DEFAULT_ENV_FILE

[Rasmus Villemoes]

I wanted this to be compatible with mkenvimage, including the ability
to embed newlines in variables by escaping them. But I failed to check
that it works more than once.

Fixes: f3d8f7dd73a (Allow providing default environment from file)
