a6a1bc9abc rtnl_route: enhance RTA_TABLE decoding 
The attribute of RTA_TABLE is not just a 32-bit integer, some constants
have well-known symbolic names like RT_TABLE_DEFAULT.

* nlattr.h (decode_nla_rt_class): New prototype.
* rtnl_route.c (decode_nla_rt_class): New function.
(rtmsg_nla_decoders) <RTA_TABLE>: Use it.
* tests/nlattr_rtmsg.c (main): Check RTA_TABLE decoding.
