meta: move some text from oe-setup-builddir to conf-notes.txt
This allows the end users to be able to override the entire notes
showing on the shell console. For instance, Our company uses a
external conf-notes.txt, and we run bitbake with some extra variables,
looks like: F=xxx D=xxx M=xxx bitbake <target>, so we want to show
exactly these texts on the shell console, that's why we need this
change.
