    oe-build-perf-test: suppress logger output when tests are being run
    
    Prevent logger from writing to stderr when the tests are being run by
    the TestRunner. During this time the logger output is only written to
    the log file. This way the console output from the script is cleaner and
    not mixed with possible logger records.
