[PATCH 3/5] env: make env_set_default_vars() return void

[Rasmus Villemoes]

Unlike most other functions declared in env.h, the return value of
this one also isn't documented. It only has a single caller, which
ignores the return value. And the companion, env_set_default(),
already has void as return type.
