- Do not hard code the number of the CAN interface to use. (This also allows specifying it via make command line / environment variable.) - Make less use of preprocessor and rely on compiler to eliminate dead branches and unused variables.

That is annoying, isn't it?
I'll add a __attribute__((weak)) board_enable_can_transceiver(can_t *dev); and a __attribute__((weak)) board_disable_can_transceiver(can_t *dev); into the periph_can driver, so that we do not need to have magic stuff at application level, but rather let the board hook into can_init().
But that is not independent of this PR and will be a follow up.

We already have a CAN transceiver interface, it's just not integrated with candev 😩

Contribution description
Testing procedure
The test should behave as before. (Unless one would pass e.g.
CAN_DEV=1, in which case the 2nd CAN interface would be used instead of the first.)Issues/PRs references
