[PATCH v3] selftests: can: enable CONFIG_CAN_VCAN as a module

[Davide Caratti]

A proper kernel configuration for running kselftest can be obtained with:

 $ yes | make kselftest-merge

Build of 'vcan' driver is currently missing, while the other required knobs
are already there because of net/link_netns.py [1]. Add a config file in
selftests/net/can to store the minimum set of kconfig needed for CAN
selftests. While at it, move existing CAN-related knobs from selftests/net
to selftests/net/can.

Notes:
    V3:
      - sort entries alphabetically (thanks Vincent Mailhol)

    V2:
      - move CAN-related knobs needed by [1] into selftests/net/can (thanks
        Vincent Mailhol); remove enabling of CAN_RAW and CAN_NETLINK since
        Kconfig already implies them
