Support wpa_supplicant debug level without log file

When -J option is passed with an empty file name, update the
wpa_supplicant debug level but do not specify log file name with -f.
This is needed to support platforms like Android where wpa_supplicant
is compiled without support for -f, and logs directly to logcat.
