[Toybox] [PATCH 2/2] dmesg: Line buffering for stdout

[Brian Norris]

In one-shot "dump the log" mode, the buffering strategy doesn't matter
too much. But when in "follow" mode (-w or -W), this means we won't
necessarily dump new log message promptly -- we'll wait until we fill
the stdout buffer (currently 4KiB).

Line buffering means we'll print things proactively, as soon as we read
them from kmsg or syslog.
