tools: Lower kdumpctl dependency to Recommends on RHEL

Most of cockpit-system works fine without kdump functionality, and the
kdump page fails gracefully without it ("Kdump service is not installed"
alert). As recommends are installed by default, this is the right
dependency level.

kdump does not currently exist on RHEL/CentOS 10 [1], so skip the test
there.
