Add setup script for easy openbmc env setup

Before this commit it was required to specify a long
TEMPLATECONF string before running openbmc-env if one
wanted to build a non-qemu image.

This commit adds a simple setup script that can be
sourced like the following to setup the environment for
any machine (e.g., for palmetto):

. setup palmetto
