samples/drivers/can/counter fails in twister for native_posix

[martinjaeger]

Describe the bug

samples/drivers/can/counter works when run using west, but fails in twister with a timeout.

To Reproduce

Set can_loopback0 to status = "okay" in devicetree and run:

west build -b native_posix -t run samples/drivers/can/counter

It works with the following output:

*** Booting Zephyr OS build v3.2.0-rc2-183-g5af0fbc2e302  ***
Change LED filter ID: 0
Finished init.
Counter filter id: 1
Counter received: 0
Counter received: 1
Counter received: 2
Counter received: 3
Counter received: 4

Now try with twister:

scripts/twister -p native_posix -T samples/drivers/can/counter

It fails with a timeout. The file handler.log is empty.

ERROR   - native_posix              samples/drivers/can/counter/sample.drivers.can.counter FAILED: Timeout

Expected behavior

The sample runs successfully in Twister.

Impact

Annoyance because the board has to be excluded from CI and the sample cannot be tested.

Environment (please complete the following information):

SHA: 5af0fbc

Additional context

Realized this during work on #50530

I'll look into this. The CAN counter sample runs fine in twister on regular hardware boards.
