rootfs-postcommands: Actually do the re-ordering

Previous commit added logic to move certain tasks to the end, but these
had no effect, because the result of the make_last() function was not
used to update the post_process_cmds variable.

Also, once this is fixed, it becomes evident that the commands need to
be joined using whitespace, otherwise they all run together, and cannot
be executed as individual commands anymore.

Fixes: 0ffff2c1f8 ("rootfs-postcommands: Try and improve ordering constraints")
