During bootloader installation sansapatcher disk access is accidentially
set up twice. This is not a problem except on Windows, which will abort
with a "permission denied" error.
This is basically the same problem as for ipodpatcher bootloader install.

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.
