Fix Calico's FelixConfiguration when "IP in IP" is disabled (#7926)

When using Calico with:

- `calico_network_backend: vxlan`,
- `calico_ipip_mode: "Never"`,
- `calico_vxlan_mode: "Always"`,

the `FelixConfiguration` object has `ipipEnabled: true`, when it should be false:

This is caused by an error in the `| bool` conversion in the install task:
when `calico_ipip_mode` is `Never`,
`{{ calico_ipip_mode != 'Never' | bool }}` evaluates to `true`:
