p54: Support boottime in scan results
This patch fixes an issue with wpa_supplicant dropping all scan results because their where considered to be "too old" (e.g.: "skip - scan result not recent enough (121056.086325 seconds too old)") which is very weird because this looks like that the scan results have been received before a scan started. This is due to the inaccuracy of the default timing mechanism for calculating the BSS entry age.
