sw test tool: Modify conditions of ofp_packet_in_reason

OF 1.4.0 spec (B.14.2 More descriptive reasons for packet-in) says:

    The main change is that the the "output action" reason OFPR_ACTION is effectively split into four reasons,
    "apply-action", "action-set", "group bucket" and "packet-out", representing the four distinct context
    where this action is used.

A set of reason values for ofp_packet_in message in OF 1.3.3 is:

    enum ofp_packet_in_reason {
        OFPR_NO_MATCH    = 0, /* No matching flow (table-miss flow entry). */
        OFPR_ACTION      = 1, /* Action explicitly output to controller. */
        OFPR_INVALID_TTL = 2, /* Packet has invalid TTL */
    };

And a new set of reason values for ofp_packet_in message in OF 1.4.0 is:

    enum ofp_packet_in_reason {
        OFPR_TABLE_MISS   = 0, /* No matching flow (table-miss flow entry). */
        OFPR_APPLY_ACTION = 1, /* Output to controller in apply-actions. */
        OFPR_INVALID_TTL  = 2, /* Packet has invalid TTL */
        OFPR_ACTION_SET   = 3, /* Output to controller in action set. */
        OFPR_GROUP        = 4, /* Output to controller in group bucket. */
        OFPR_PACKET_OUT   = 5, /* Output to controller in packet-out. */
    };

Therefore, "reason != OFPR_ACTION" means "reason == OFPR_NOMATCH or reason == OFPR_INVALID_TTL".

NOTE: OFPR_TABLE_MISS is defined as OFPR_NO_MATCH in ryu.ofproto.ofproto_v1_4.

sw test tool: Modify OFPMatch to normalize

This patch is for avoiding the following issues when using ofproto_v1_4_parser:

  - OFPMatch that is created from JSON keeps unicode strings, instead of usual strings.
  - In OFPMatch that is created from JSON, IPv6 formats like 'ff::0' or '00ff:0000:0000:0000:0000:0000:0000:0000' are not normalized to 'ff::'.
