[Development] Adding 3rdpary libraries to QtSerialBus

I'm currently trying to find this out. What I know so far, is that
you can compare "something" to

#define ARPHRD_CAN	280

to find out the interface is of type SocketCAN. As there are more of 
these definitions in /usr/include/linux/if_arp.h, a generic way to get 
the "type" of an interface could be added to QNetworkInterface.

Maybe someone with more Linux programming knowlegde has a hint - 
libenumif surely knows it, but looks like a sledgehammer for my small 
problem.

Cheers,
Andre
