T7658: Fix default max-map-count and add smoketest for this parameter

[natali-rs1985]

In the code we have the restriction not to decrease values in host-resources section. We need to skip this smoketest for now until we remove the restriction because it will always fail

Please add a smoketest to check this feature and actual settings of the sysctl.
As it wasn't working for months.

Added smoketest

The change is sensible and there's a test, no objections.

[sever-sever]

If we delete the max-map-count option, the expected default value is 65530 and not 100_000

Close this PR due to moving functionality to "system option host-resources"
