iwd: Use same signal strength calculation as wpa_supplicant
Fixes the signal strength reported by connman being lower when using iwd
compared to wpa_supplicant.
In the wifi plugin for wpa_supplicant, the signal strength is calculated
as follows:
strength = 120 + g_supplicant_network_get_signal(supplicant_network);
if (strength > 100)
strength = 100;
The g_supplicant_network_get_signal() function returns the signal
strength in dBm. This means the signal strength calculation in connman
for wpa_supplicant treats -20 dBm or higher as 100% signal strength.
The iwd plugin is changed to use the same calculation but as iwd returns
returns the signal strength as 100 * dBm, it needs to be divided by 100
to get the same dBm value as wpa_supplicant.
