Subject: [PATCH] Just test that config file is readable

Test that the config file is readable (ie. "-e") before dying, not
strictly a file ("-f").

This allows one to more-easily generate dynamic configuration files
and pass them via `apt-mirror /dev/stdin` rather than having to create
temporary files.

Closes: #824493
