Agent will install even if sysetmd is in degraded mode

[Albert-LGTM]

Proposed changes

• The OpenBAS agent install fails if Systemd is in degraded mode. This mode occurs if one or more (unrelated) systemd services failed to start.

Related issues

• Improve systemd check for Linux scripts #70
• I was unable to install the OpenBAS Agent on my system due to my Systemd being in degraded mode. With these changes I was able to install the agent successfully.

Checklist

• I consider the submitted work as finished
• I tested the code for its functionality
• I wrote test cases for the relevant uses case
• I added/update the relevant documentation (either on github or on notion)
• Where necessary I refactored code to improve the overall quality
• For bug fix -> I implemented a test that covers the bug

Hi @Albert-LGTM, good thinking! Thanks for your contribution.

As a policy, we require pgp-signed commits for inclusion into the repository, would you consider amending the PR to sign the commits?

Apart from that, it looks like this change should be replicated in the other linux-specific -installer and -upgrade scripts.

I have now renamed the variable to systemd_status and updated every agent linux script to accept systemd in degraded mode

That's great, thanks. We'll get on that ASAP, and keep you posted.
