android: multinode-target: disable kernel messages during critical synchronization
Specifically on HiKey, when the adb daemon is restarted it causes kernel
messages to flood the console. These messages can easily confuse the
LAVA dispatcher signal handler and cause poor test reliabilty.
This patch reads the current kernel messaging levels into a file, sets them
to the lowests values, and restores them after the critical synchronization
steps have finished.
