Currently, querying a unit's available memory would result in infinity if there are no limits set on the unit or ancestors. That undermines semantics implied by the name, so look at the physical memory if the search propagates up to the -.slice. This makes sense even in systemd user instances, limits of -.slice are still looked at too. Also change printed representation of infinite MemoryAvailable which means we could not figure out a good estimate.
