ubus: set scan duration to roam scan interval

Browse Source 
Some clients seem to ignore scan requests with unreasonably high
measurement durations. This was observed with a Google Pixel 4A as well
as a Xiaomi Mi 10T.

Advertise a scan duration which closely matches the roam scan-interval.
This triggers scans more reliably with the aformentioned devices.
