Fixes #560 - Add systemctl wants to foreman.target for httpd

[qcjames53]

Why are you introducing these changes? (Problem description, related links)

When running systemctl start foreman.target, Apache (httpd) does not start on it's own. I attempted to include this as a part of the fix in #536 but biffed the implementation.

What are the changes introduced in this pull request?

• Corrects foreman.target's wants to properly include httpd. The old add-wants block was skipped by systemctl due to httpd being in the multi-user.target (higher prio). This was fine unless the user manually wanted to run systemctl stop foreman.target and systemctl start foreman.target, which might sometimes be the case.

How to test this pull request

Steps to reproduce:

1. Pull changes and rebuild the VMs.
2. Run vagrant ssh quadlet after VM boot.
3. Wait for services to spin up, then run systemctl list-dependencies foreman.target to verify httpd made the list.
4. Run systemctl stop foreman.target and systemctl status httpd to ensure it stopped.
5. Run systemctl start foreman.target and systemctl status httpd to ensure it is running.
6. Validate unit test changes.

Why did this need to move?

[qcjames53]

The foreman.target needed to be created before the httpd task used it for my previous add-wants approach. I just moved it back in the newest push.

Err sorry, this is kind of a weird assertion. I think if we are going to test anything, then we should test that the httpd.service has what we expect.

[qcjames53]

Agreed. Asked Claude to fix the unit test but missed that it changed this line to something weird. It should assert on the actual string now.

Working nicely for me:
