SupplicantHal/HostapdHal: Wait for death

When wpa_supplicant/hostapd is being terminated, ensure that we block
for a small timeout (50 ms) to ensure that the daemon is indeed dead. This
prevents a potential race when wifi/tethering is quickly toggled & the
previous instance of the daemon is not fully terminated before the next
toggle on.

Bug: 134729435
Test: Manually toggled wifi/tethering multiple times in quick
succession.
Test: Will send for full regression testing.
