ping: op-mode: T2762: always run in default VRF unless defined otherwise

When connected to VyOS by SSH through any VRF, every command is executed
in the VRF context thus e.g. ping will run in VRF context but no VRF was
defined on the CLI.

ping should always run in the default VRF no matter where it is executed,
unless a VRF instance is explicitly defined by CLI.
