libagentx add agentx_varbind_unsigned32

[Martijn van Duren]

To prevent any future confusion around unsigned ints I'd like to add
agentx_varbind_unsigned32 as an alias to agentx_varbind_gauge32.

According to RFC 2578 section 2:
-- an unsigned 32-bit quantity
-- indistinguishable from Gauge32

OK?
Still OK to ride yesterdays bump?
