oeqa/utils/qemurunner.py: Fix HIGH CPU usage on LoggingThread
LoggingThread is used for receive console output from QEMU over TCP, so add filter to only wake poll on read events, also change the event mask variable name to be more descriptive. This fixes HIGH CPU consume caused by wake on ready to write events. Signed-off-by: Aníbal Limón <anibal.limon@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
