opendmarc hist file arc value is wrong

[mschneider82]

the documentation:
https://github.com/trusteddomainproject/OpenDMARC/blob/master/opendmarc/README#L183

says that the value should be 0 = pass or 2= fail
it also says that arc_policy is the same value. In my .dat file it shows:

arc 7
arc_policy 2 json:[]
action 2

because the value of arc is using ARES_RESULT_FAIL which is 7: https://github.com/trusteddomainproject/OpenDMARC/blob/master/opendmarc/opendmarc.c#L2360
