Subject: classes/logging: make shell message functions output to the console

Use the FIFO that is now set up when executing tasks within BitBake to
make bbdebug/bbnote/bbwarn/bbplain/bberror/bbfatal output to the console
through BitBake's UI (as their python counterparts do) instead of only
outputting to the task log.

Note that this requires the corresponding change in BitBake that creates
the FIFO; without it such messages will end up in a file where the FIFO
should have been (but won't cause any other ill effects).

Remainder of the fix for [YOCTO #5275].
