Reset persist.log.tag while running testing
The system property changes the default log level for "all" log tags
even including the unique tag that this test uses. So, if it is set in
DUT, testing the behavior of APIs like __android_log_is_loggable
becomes impossible, because the system property can override the log
level that is given to the API by the test.
Work around this issue by resetting the system property while running
this test. It is restored to its original value (if it had one), after
the test is done, either successfully or not.
