You cannot fork the process to background (-B) and record the log to
stdout. stdout is closed whenever -B is included in the command line and
this will stop any logging. If you want to get the stdout stored to a
file, you would need to either keep the process on foreground or use a
command like "wpa_supplicant .... > /tmp/log &".
