libubootenv: move in fw_env.config

Currently we have downstream/upstream Toradex uboot recipes and we dont
want to add fw_env.config for both of them to avoid code redundant.

Let's add fw_env.config to libubootenv, which will be installed for
both donwstream/upstream distros.

Change libubootenv to a machine arch recipe since now it has machine
specific fw_env.config files.
