configd: T3694: always set script.argv

Several scripts imported by vyos-configd (including
src/conf_mode/protocols_static.py) rely on argv for operating on VRFs.
Always setting script.argv in src/services/vyos-configd ensures those
scripts will operate on the default VRF when called with no arguments.
Otherwise, a stale argv might cause those scripts to operate on the last
modified VRF instead of the default VRF.
