uec-publish-tarball does not show errors from uec-publish-image

Binary package hint: cloud-utils

$ uec-publish-tarball mytar.tar.gz mybucket x86_64

The above will correctly exit with failure if one of the underlying calls to euca-* fails. However, it will not show the user the output of those euca tools. This is because uec-publish-tarball captures the stdout of the call to uec-publish-image (which calls euca tools). The stderr is correctly passed through. The problem is that the euca2ools are writing (some) errors to stdout rather than stdin. That stdout was being consumed and not sent to the user even on non zero exit

So, the work around here is to print uec-publish-image's output to the user when the call to uec-publish-image fails.

Also noticed here that the error message printed by uec-publish-image contains a trailing '%s' which just looks confusing.
