Denton Gentry d7f452c0a1 net/portmapper: send discovery packet for IGD specifically.
There appear to be devices out there which send only their
first descriptor in response to a discovery packet for
`ssdp:all`, for example the Sagemcom FAST3890V3 only sends
urn:schemas-wifialliance-org:device:WFADevice:1

Send both ssdp:all and a discovery frame for
InternetGatewayDevice specifically.
