create_slcan.sh: slcan0 has not been successfully created

The issue was reported twice. But I can't reproduce it at the moment.

Setup 1:

• Ubuntu-22.04
• Docker Desktop (6.8.0-49-generic in host OS, 6.10.11-linuxkit inside Docker)
• Wayland

Setup 2:

• WSL

Well, probably, slcan doesn't like virtualization.
