target/cloop: cleanup
Remove the code to build the cloop utilities for the host (it is now in package/cloop). Use fakeroot instead of ugly sudo. The cloop filesystem generation code is now much more similar to other filesystems code. Remove empty Makefile.in. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
