bgpd: allow value 0 in aigp-metric setting

The value of 0 is accepted from peers, and can also be set by the
route-map "set aigp-metric igp-metric". For coonsistency, it should
be allowed in "set aigp-metric <value>" as well.

    Set the BGP attribute AIGP to a specific value. If ``igp-metric`` is specified,
    then the value is taken from the IGP protocol, otherwise an arbitrary value.
