Bor Grošelj Simić dcb8f3d224 main/openssh: 'UseDNS no' is already in the default config
Upstream changed the default some time ago

From the 6.8 changelog:

```
Changes since OpenSSH 6.7
=========================

This is a major release, containing a number of new features as
well as a large internal re-factoring.

Potentially-incompatible changes
--------------------------------

 * sshd(8): UseDNS now defaults to 'no'. Configurations that match
   against the client host name (via sshd_config or authorized_keys)
   may need to re-enable it or convert to matching against addresses.
