kdump test: Let "kdumpctl start" to output the kdump test status

Resolves: RHEL-96939

Currently "kdumpctl restart" will show the kdump test status to users,
also add this to "kdumpctl start", so users can know this as early.

In addition, "kdumpctl start" shouldn't return the value of
check_vmcore_creation_status(), so "exit 0" is used after
check_vmcore_creation_status().
