sw test tool: Correct the comparison method to treat matches as the set

Browse Source 
OF 1.3.3 spec (3 Glossary) says:

    Flow Entry: an element in a flow table used to match and process packets. It contains a set of
    match fields for matching packets, a priority for matching precedence, a set of counters to track
    packets, and a set of instructions to apply (see 5.2).

According to OF spec, the match fields are treated as the set.
This means that the order of matches which flow_stats message returns is inconsistant.
This patch corrects the comparison method of matches by sorting in a particular order before comparison.
