[PATCH 10/18] tests: check for WPA_TRACE messages in hostapd log

[Benjamin Berg]

From: Benjamin Berg <benjamin.berg at intel.com>

Otherwise the tests will simply pass even though e.g. a memory leak or
other error is reported. So read the log file and raise an exception
when it contains the 'WPA_TRACE:' string.
