packet lib: bgp: fix reversibility about json

although BGP is using internal classes, no class is registered into '_class_prefixes'.
therefore, from_jsondict() does not work correctly.
this patch makes from_jsondict() to work correctly by registering internal classes into '_class_prefixes'.

examination code:

    from ryu.lib.packet import bgp
    msg1 = bgp.BGPUpdate(withdrawn_routes=[bgp.BGPWithdrawnRoute(length=0, addr='192.168.0.1')])
    print msg1
    jsondict = msg1.to_jsondict()
    msg2 = bgp.BGPUpdate.from_jsondict(jsondict['BGPUpdate'])
    print msg2
    print str(msg1) == str(msg2)

before applying this patch:

    BGPUpdate(len=None,marker='\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff',nlri=[],path_attributes=[],total_path_attribute_len=None,type=2,withdrawn_routes=[BGPWithdrawnRoute(addr='192.168.0.1',length=0)],withdrawn_routes_len=None)
    BGPUpdate(len=None,marker='\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff',nlri=[],path_attributes=[],total_path_attribute_len=None,type=2,withdrawn_routes=[{'BGPWithdrawnRoute': {'length': 0, 'addr': '192.168.0.1'}}],withdrawn_routes_len=None)
    False

after applying this patch:

    BGPUpdate(len=None,marker='\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff',nlri=[],path_attributes=[],total_path_attribute_len=None,type=2,withdrawn_routes=[BGPWithdrawnRoute(addr='192.168.0.1',length=0)],withdrawn_routes_len=None)
    BGPUpdate(len=None,marker='\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff',nlri=[],path_attributes=[],total_path_attribute_len=None,type=2,withdrawn_routes=[BGPWithdrawnRoute(addr='192.168.0.1',length=0)],withdrawn_routes_len=None)
    True
