mvebu: base-files: Update Turris Omnia U-Boot environment
Move the update procedure from sysupgrade to first boot, which is much more convenient in the sysupgrade case (otherwise the environment is always one generation behind). Check whether we have an old U-Boot release installed, and update the environment only if necessary. Some notes on the U-Boot environment: The first 9 lines are a copy of the default environment of the old U-Boot release - only modified, to run "distro_bootcmd", in case "mmcboot" fails to boot the factory OS. The remaining 16 lines are a backport of the default environment of the new U-Boot release (shipped with CZ11NIC23). The main entry point is "distro_bootcmd", which eventually sources boot.scr. This way, we have a unified boot protocol for all Turris Omnia revisions so far. This commit also fixes a shortcoming of previous Turris Omnia support: Users may install OpenWrt with the Turris Omnia in factory state (i.e. invalid environment store). In that case, neither fw_setenv, nor U-Boot itself, would import the default environment from the image - screwing up the rescue system, at least!
