Allow multiple file names to be listed in
BR2_TARGET_UBOOT_ENVIMAGE_SOURCE, concatenating them in the order
listed.

This allows the bulk of the environment to be shared across multiple
boards using a common environment file with board-specific values
supplied in a secondary environment source file.

The lines following the pipe should have been indented by one more tab
(but it admittedly wasn't done so far). I've fixed that up and applied
your patch to our next branch.

Thanks, and sorry for the long delay!
