socketcan: Make find_available_interfaces() find slcanX interfaces

[msalau]

Hello,

This change allows can.detect_available_configs(['socketcan']) find not just canX and vcanX interfaces, but also slcanX interfaces too. Such names are given by default to interfaces that are created using the slcand utility.

The module has an option to work with SLCAN adapters directly, but creating a SocketCAN interface instead can be beneficial too (e.g.: make it possible to use Wireshark, can-utils, cantools and etc.). For this reason I added few lines to the doc about how to use SLCAN adapters with socketcan.

Regards,
Maksim
