rbutil uses several components from the utils folder, and can be
considered part of utils too. Having it in a separate folder is an
arbitrary split that doesn't help anymore these days, so merge them.
This also allows other utils to easily use libtools.make without the
need to navigate to a different folder.

The build system used by rbutil is not very robust: all the files
are eventually compiled to the same directory so we cannot have
two files with the same name (system.c would conflicts with
system.cpp) so rename one file to avoid this. Also change all
include directives to local ones because we don't have to expose
the entire mspack source to inclusion.
