Missing var sshd_config_path for RedHat-8

[FrankGiesecke]

If the target system relies on RedHat 8, the role throws an error.

TASK [arillso.sshd : set hostkeys according to openssh-version] ****************
fatal: [****]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'sshd_config_path' is undefined\n\nThe error appears to be in '/builds/mw/infrastructure/ansible-management/projects/internal-server-landscape/.ansible/roles/arillso.sshd/tasks/distribution/subtasks/crypto.yml': line 4, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: set hostkeys according to openssh-version\n  ^ here\n"}

The reason for this is, that the file vars/RedHat-8.yml doesn't contain the definition of sshd_config_path.

The variable is also missing in:

• vars/Oracle Linux-8.yml

Closes #22

Mind adding a Rocky-8.yml to support rocky linux with this PR?

@felixb It might be better to create a single Issue for rocky linux support with all necessary information and fix this in a separate pull request.
Feel free to mention me in the issue and I will create a fix for this.

created a quick PR in #31

So, let us hope that the PRs will be merged.
