[pseudo][PATCH 17/23] pseudo_util: Ensure pseudo_setupenvp handles memory consistently

[Mark Hatle <mark.hatle@kernel.crashing.org>]

From: Richard Purdie <richard.purdie@linuxfoundation.org>

Most of the new environment values added to the new environment array
returned by setupenvp are already freshly allocated memory. Ensure all
the returned values are so the data can be handled consistently and
correctly freed (for a later patch).
