hiba: Add initial recipe for hiba

Discussion to install the HIBA Internal OpenSSH to fetch dependencies
can be found in
https://lists.openembedded.org/g/openembedded-core/topic/94475279#172977

HIBA is a system built on top of regular OpenSSH certificate-based
authentication that allows to manage flexible authorization of
principals on pools of target hosts without the need to push customized
authorized_users files periodically.

This recipe allow us to manage SSH to production machines easily and not
rely on authorized keys.

Tested:
Ran the local-setup.sh and works fine on a BMC.
```
$ ssh -F /tmp/tmp.w8itTW/ssh_config -p 2201 root@localhost

prodHost: limited access
Connection to localhost closed.
$ ssh -F /tmp/tmp.w8itTW/ssh_config -p 2202 root@localhost
