[PATCH 10/11] chardev: force write all when recording replay logs

["Alex Bennée" <alex.bennee@linaro.org>]

This is mostly a problem within avocado as serial generally isn't busy
enough to overfill pipes. However the consequences of recording a
failed write will haunt us on replay when causing the log to go out of
sync.
