tree.sh: fix up copy_elf(), bad for loop

Because of how sh works, having just the [] line causes
sh to exit, annoyingly without an error message, but it
does cause a non-zero exit.

This bug will have already been triggering, before I added
the recent error handling on files for this for loop.

also do it to the other loop in lib.sh
