Paul Eggleton 614cbeddc8 bitbake: lib/bb/msg: introduce logger_create() function

We use this code to set up a logger with colour in a number of different
places, so create one function that does this and make some of bitbake's
utility scripts use it.

(Bitbake rev: b1ba7d1cc8ec33e2d081230287abd07f52136097)
