dropbear: Disable the Chacha20-Poly1305 cipher
The BMC dropbear SSH server has the affected chacha20-poly1305. The
dropbear project indicates that it's affected but not vulnerable to the
terrapin attack:
```
https://github.com/mkj/dropbear/blob/17657c36cce6df7716d5ff151ec09a665382d5dd/CHANGES#L17
```
The options are to remove the affected chacha20-poly1305 algorithm, or
to enable the new strict-key exchange (strict-kex) option although the
client would also need to use strict-kex.
Go with the first option.
Tested:
Before change:
```
root@p10bmc:~# ssh -c help
ssh: Available ciphers: chacha20-poly1305@openssh.com,aes128-ctr,aes256-ctr
```
After change:
```
root@p10bmc:~# ssh -c help
ssh: Available ciphers: aes128-ctr,aes256-ctr
```
