This makes the age information for cfg80211 scan results more accurate and fixes issues with wpa_supplicant dropping "old" scan results (e.g., "wlan0: Own scan request started a scan in 0.000456 seconds") that looked like would have been received before a scan started due to the inaccuracy of the default timing mechanism for calculating the BSS entry age. This makes hwsim test cases significantly more robust to run.
