[PATCH v2] tests: Fix Permission denied on Fedora

[Masashi Honma]

On Fedora 26, start.sh fails with these error messages.

Failed to connect to wpa_supplicant global interface: /tmp/wpas-wlan0  error: Permission denied
Failed to connect to wpa_supplicant global interface: /tmp/wpas-wlan0  error: Permission denied
...

This is because Fedora 26 uses "wheel" group as administrative group.
