bitbake: knotty: Drop task prefix of PLAIN log messages

To quote Paul:

Not that long ago we added a prefix to logged messages to allow us to see
where the message has been generated (recipe / task). This is undoubtedly
useful for errors and warnings, however, I'm not sure it's really appropriate
for bb.plain(). As an example, see the output for -c listtasks now:

...
NOTE: Executing RunQueue Tasks
nodejs-native-4.5.0-r0 do_listtasks: do_addto_recipe_sysroot
nodejs-native-4.5.0-r0 do_listtasks: do_build                      Default task for a recipe - depends on all other normal tasks required to 'build' a recipe
nodejs-native-4.5.0-r0 do_listtasks: do_checklicense
nodejs-native-4.5.0-r0 do_listtasks: do_checklicenseall
nodejs-native-4.5.0-r0 do_listtasks: do_checkpkg
...

This patch excludes PLAIN messages from this prefixing making the log output
neater.
