setup-interfaces: find essids when SSID List capability present
When a essid has the 'SSID List' extended capibility, the `find_essids`
function will not return that ssid. That's because the `$1 ~ /SSID/` awk
pattern will match that line. The ssid variable then is set to an empty
value because there is no `:` (field separate) in that line, so `$2` is
empty.
The terminator of the statemachine then skips this essid, because it
checks if the `ssid` variable is not empty.
We can fix this by making sure the field ends with `SSID`, which is not
the case with the `SSID List` line.
Partial output of `iw dev wlan0 scan`:
```
Extended capabilities:
* Extended Channel Switching
* TFS
* WNM-Sleep Mode
* TIM Broadcast
* BSS Transition
* SSID List
* Operating Mode Notification
* 6
* Max Number Of MSDUs In A-MSDU is unlimited
```
