[6.16.z] Narrow down host's subscription status check

[Satellite-QE]

Cherrypick of PR: #17378

Problem Statement

It looks like the host's subscribed() property can potentially return wrong value from sys-purpose status.

# subscription-manager status
+-------------------------------------------+
   System Status Details
+-------------------------------------------+
Overall Status: Disabled
Content Access Mode is set to Simple Content Access. This host has access to content, regardless of subscription status.

System Purpose Status: Unknown

All credit goes to @jeremylenz who noticed this!

Solution

We should check the Overall Status specifically.
