Allow debug log to be written to both syslog and file

Browse Source 
If hostapd or wpa_supplicant is started with both -s and -f command line
arguments, debug log ended up being written only into syslog and the log
file was left empty. Change this so that the log entries will be written
to both places. Either -s or -f (or both) results in debug log to stdout
being disabled which was already the case.
