Only manage the actual DNS entry named by the `dns-name` argument.

The original version of this program (written for another project) laid claim to the entire subtree under the target DNS name, as part of a broader feature of adding both per-instance hostnames and a per-ASG hostname with multiple records. This program doesn't do that; however, I forgot to remove this behaviour when porting the code.

This was caught in production, of course, though without any damage. An attempt to manage `grimoire.ca` failed because the AWS identity it ran under didn't have permission to do anything other than modify A and AAAA records.
