sort {delete,check}-old*

[emaste]

Summary

It is more convenient to review old libraries, files, and directories in order.

Sort check-* after checking for existence of files for efficiency, and because /usr/lib/debug entries are added while iterating over the list.

[brooks]

This seems fine.

As an aside: this code is appallingly slow and needs to be replaced with something that doesn't require 8+ execs per file that might exist.
