Subject: [PATCH] Enable null globs when scanning for config.d/*.sh

Without this, an empty directory leads to an false error complaining that the file `/etc/dehydrated/config.d/*.sh` is not readable or doesn't exist.

With `nullglob` set, the glob, if it doesn't match anything, will expand into null rather than returning the glob string, causing an empty config.d folder to not throw an error.
